The future of mambo in GPL is Joomla!

 Joomla! is a Content Management System (CMS) created by the same award-winning team that brought the Mambo CMS to its current state of stardom. 
The name Joomla! is a phonetic spelling for the Swahili word "Jumla", which means "all together" or "as a whole". It was chosen as the entire teams behind Mambo were unanimous in their commitment to protecting the interests of the creators and community, which was the true cause for the success and acclaim earned by that project.

This name was chosen from thousands of recommendations by the community, and even went through an arduous review session by branding and marketing professionals who also felt that Joomla! was the best choice of the lot.

What sets Joomla! apart from the rest is our dedication to keeping things as simple as possible, while providing the most features possible. Finally, non-technical people can have complete control over their websites without paying exhorbitant amounts for closed, proprietary software.

Joomla! is more than just software, it is people. The community behind Joomla! includes developers, designers, systems administrators, translators, content writers, and most importantly the end users. We welcome you to our community, and look forward to the future with great excitement! from http://www.joomla.org
