homepage: www.activecollab.com

Easy to install and use – activeCollab uses set of simple tools to provide environment for collaboration. Using this simple tools you can discuss with other team members, plan the execution of the project, assign tasks, attach files, send notifications. Most of the objects in the system are taggable so you can use tags and search to easily find specific information.

Tools included in activeCollab:

• Run as many projects as you wish
• Post messages that people can comment. Email notifications included
• Milestones for marking important steps in project execution
• Assign tasks to people involved in the project
• Attach unlimited number of files (file size is limited only by your web server, not by activeCollab). Files support versioning and comments
• Search through every object in project, including text based files you uploaded

Install it on your own server – activeCollab is a script that you install on your server so you have full control over your data and you can customize it to fit your specific needs. In installation package there is a tool that will help you set up activeCollab in a matter of minutes. Unpack the archive, upload the contents to your server and follow five easy steps and you are good to go. Installer will write configuration files, create tables in database and import initial set of data including administrators account and your company info.

And you should not worry about upgrades – they are also automated. Just upload new files and execute upgrade script. Everything else is done for you.

Portable – activeCollab is made in PHP programming language and that makes it really portable. You can run it on your web server, your home computer or even from your USB stick.

Web based – Once you have activeCollab installed on your server only thing you’ll need to use it is web browser. Most of the modern browsers are supported (Internet Explore 6, Mozilla Firefox etc). Much better support will be provided when we release 1.0 – there will be many interface enhancements and it will be tested by more people on many different platforms and installations.

100% free, 100% open source – You can use activeCollab free of charge. It is release under the terms of Honest Public License. See the license.txt file that comes in the installation package for more details. Here’s what you can and what you can not do:

• You can use activeCollab free of charge.
• You can redistribute it without any limitations.
• You can make modifications and while they are used in-house they can stay closed. If you start distribution of modified system you need to make modification publicly available under the terms of General or Honest Public License.
• You can’t charge for the software itself even if it is modified.
• You can charge distribution, reproduction, bundling and packaging costs. You can also charge for support and charge for indemnification.

The whole point is about sharing, not just using.

No limitations – Some systems are limited by the number of users, clients or projects that you can have at the same time. activeCollab comes without such limitations. You can have as many projects (client companies, users, task lists or anything else) as you need.

Per project permissions – You can have two types of projects:

1. internal projects where only your company is involved in development
2. project where you have one or many client companies involved

In both cases there is permissions system that enables administrators to set up access permissions to specific companies and users, even for the members of your own team. You want Peter to have access to Project A and Project B but you don’t want him around Project C. Not a problem.

You can also limit access permissions for specific tools in a project. So, you can give access to messaging part of the project to some of your clients, but restrict file upload and task management.

Private data – Some objects have option to be marked as private. In that case only members of owner company that have access to specific project will see it and be able to manage it. Clients will not be aware of existence of that objects (message, milestone, task list…)

Private data remains private among members of owner company.

Symphony has a bucket-load of features, but rather than tell you about them all, it’s better to let you discover them for yourself. Check out the live demo or download the Symphony installer and try it for yourself. Below is an overview of Symphony’s main features.

Designed to do things your way

Symphony lets you organise everything the way you like, from your publishing environment to your website’s URL structure. Built to be versatile and customisable, Symphony really is what you make of it.

Powered by XML and XSLT

Symphony’s templating engine is pure XSLT goodness. XSLT is a standard recommended by the W3C, so learning Symphony means that you’re learning skills that you can also use outside of the system. If you already know the XML and CSS standards, then chances are you should be able to quickly pick up XSLT.

Symphony allows you to create small blocks of XSLT code called utilities, which you can use as building blocks to construct your site’s pages. Due to the nature of XSLT, these utilities are highly reusable, so the next time you’re developing a website you’ll probably find you’ve already done half the work.

There’s no need to bother with complex SQL queries; Symphony can take care of the heavy lifting while you just worry about what data you’d like. Of course, if you want to write the queries yourself (or maybe a PHP event on page request), you can.

Rapid developement means more time to relax

It takes 4 minutes to setup and install Symphony. It takes 3 clicks to install Campfire services (our extension system), 2 clicks to update the system and 1 click to get the latest stats on your website. Symphony is about getting things done quickly.

Features

The Engine

• Symphony is modular, which makes it a cinch to move your files between different websites, collaborate on a single project and share themes with the Symphony community.
• Of course, if there is something Symphony can’t do, there’s no problem. Campfire services, Symphony’s extension modules, can add extra functionality where it’s missing.

The User Interface

• By making every aspect of the publishing environment customisable, Symphony gives you complete control over how you and your authors publish. Every field is customisable and reorderable, and you can even apply validation rules which make sure they are correctly formatted.
• You can manage everything from within the admin interface, but Symphony is also designed to work with FTP, so if you’d rather edit files directly on the server or with your favourite text editor, you can. All your changes will be reflected in Symphony and on your website immediately.
• Symphony’s XML-RPC Campfire services allows desktop applications like MarsEdit to publish entries to your website remotely.

The Development Environment

• Maintenance mode is very useful for testing and debugging a live site. Switch on maintenance mode and visitors will be directed to your maintenance page, while you can still see and browse your website as normal. A set of handy debugging features are also enabled during maintenance.
• URL schemas give you a clean and efficient way to create dynamic pages.
• Did we mention that XSLT is a very cool templating language?

Requirements

Your Server

• PHP 4.3
• MySQL 3.23 and above
• XSLT Support (LibXSLT or Sablotron)
• Some common modules: XML Support (LibXML), ZLib Compression Library and mod_rewrite Apache module

Your Browser

• The Symphony admin requires that you use a modern standards-compliant browser. We recommend Firefox and Safari.
• For the best experience, make sure you have cookies and JavaScript enabled.

With integration, you can login from any page, display top posters, display forum stats, integrate usergroups, and so much more!Search Engine-Friendly URLs
The robots used by search engines have problems with dynamic pages that are created by most Content Mangement Systems. However, Subdreamer converts dynamic URLs into static URLs so that they can be indexed! For example, a link such as: subdreamer.com?index.php?categorid=2 would be rewritten to subdreamer.com/features.

Image Manager

No longer will you need to open your FTP program to upload images. Subdreamer provides an Image Manager to sort through, resize, and upload images on to your website. This makes it incredibly easy to add news images to articles and overall keep track of all your images.

The Plugin System

Preinstalled Plugins
13 plugins come preinstalled with Subdreamer CMS, meaning you will be able to use these plugins right out of the box:

Downloadable Plugins
In addition to the preinstalled plugins, you will be able to download new plugins that are developed by the Subdreamer Team and the community. Many of these plugins provide amazing new functionality and actually compete against standalone applications, best of all these plugins can be downloaded for free once you’ve purchased your Subdreamer CMS license.

Based on the best practices of web development, thoroughly tried on several active websites, symfony aims to speed up the creation and maintenance of web applications, and to replace the repetitive coding tasks by power, control and pleasure.

Symfony provides a lot of features seamlessly integrated together, such as:

• simple templating and helpers
• cache management
• smart URLs
• scaffolding
• multilingualism and I18N support
• object model and MVC separation
• Ajax support
• enterprise ready

New Features in 1.0

• Easier installation and larger compatibility. Symfony is now compatible with magic_quotes_gpc set to on and PHP 5.2. Pake and phing are now bundled with the core classes, so symfony has no more external dependency. It is very easy to link a symfony application to the symfony libraries (through the config/config.php file), and PEAR is no more a prerequisite. The symfony command line now works out the box (for PEAR, SVN or .tgz).
• Major performance improvement. Many parts of the code have been refactored, with performance in mind. The result is a performance increase of 50% to 500%, depending on your platform.
• New plugin system. Extending symfony has never been easier. A plugin can package classes, modules, helpers, filters, web assets, fixtures, data models, unit tests, and so on. Plugins can be installed with one command. Check the Plugins page for a list of already available plugins.
• New unit test library. Symfony is now bundled with its own unit and functional test framework, called lime, and a bunch of automated tests utilities, such as the sfTestBrowser and sfDomCssSelector classes. Symfony itself has more than 2800 unit and functional tests that guarantee its quality of code.
• Updated default pages for error 404, error 500, insufficient credentials, unavailable page, and deactivated application (thanks justinm for the design!). These pages are both much nicer and much easier to customize than before.
• Easier templating. Components and components slots now work perfectly on every situation, even with cache set to on. Their code was refactored to be fast and effective. The new temlate fragment tools, called slots, are faster than component slots, require no extra file or configuration to add a dynamic zone to a layout. And the icing on the cake: Ajax actions have no layout by default.
• Better and more flexible Model layer. Symfony is now ORM independent: it is still bundled with Propel by default, but can work with others (such as Doctrine) in a snap. Database schemas can now be written in YAML instead of XML. Persistent support and specific database encoding are now supported natively.
• New mixin feature. The sfMixin class introduces mixins in PHP, allowing core classes modification without inheritance, addition of new methods to existing classes, and multiple inheritance.
• New behaviors for Propel classes. A behavior is a group of properties and methods that can alter the Propel generated classes. To make a Propel class sortable, to add a pessimistic lock, or to change the deletion by a is_deleted flag, you now need only one line of code with behaviors.
• More user-friendly development tools. The symfony logs and the web debug toolbar now display more information about time and execution bottlenecks, thanks to the new sfTimer class. The symfony command line now has a color output (in *nix). The logging mechanism (via the sfLogger class) is more flexible and easier to extend. Logs rotation and cleaning are automated.
• More flexible filter system. User filters can now be registered anywhere in the filter chain (even before the security filter).
• New many-to-many relationships are now supported in the admin generator.
• Easier deployment. The freeze task is implemented and fully functional. It transforms a symfony project into a self sufficient program by adding in the symfony libraries and assets.
• Updated creole, Propel, script.aculo.us (1.6.5) and prototype (1.5.0_rc1)
• And more than 200 bug fixes and small enhancements
