Joomla

Joomla is an open source content management system for building professional Web sites. It can deliver a robust enterprise-level Web site, empowered by endless extensibility for your bespoke publishing needs. Joomla is different from the normal models for content management software. For a start, it's not complicated. Joomla has been developed for everybody, and anybody can develop it further. Similarly to the Firefox browser, the core system can be extended via installable add-ons authored by the developer community.
