Joomla

One of the most powerful CMSes on the Web

Joomla is the CMS of choice for designers and developers because of its high degree of customization. Its interface may not be as user-friendly as WordPress, but even so, it powers 2.6% of all the sites on the Internet because of its simple authentication and user management, as well as its strong internal search statistics and link tracking. Built-in help features, combined with a very active volunteer community, make support feedback easily accessible.
