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.
What’s new in this version: Version 1.7.3 is a security release.
