Open Source CMS

Developed by: Open Source CMS
Type of resource: web site
Target audience: General
Cost: Free access

As it states, this site encourages you "try before you install" by allowing administrator access to multiple PHP-based free and open source software content management systems, in their default installations. The long list of installations to choose from includes what the site terms as "portal" CMS such as Drupal, Joomla, Civic Space, PostNuke (and dozens more) as well as blogs, wikis, e-learning, e-commerce and group ware systems. To see which system best suits your needs, you can explore the look and feel of the CMS backend for two hours, before the systems are automatically reinstalled. The site includes forums for each CMS as well as FAQ's.
