Open Source CMS

OpenSourceCMS was created with one goal in mind. To give you the opportunity to "try out" some of the best php/mysql based free and open source software systems in the world. You are welcome to be the administrator of any CMS system here, allowing you to decide which system best suits your needs.

What a great idea. A single centralized location to give some of the more popular open source PHP projects a test drive.
