im seeing alot about Joomla around the forums, so i figured i would check it out in the cpanel and see what all the hype was about. After looking through all the information in the cpanel as well as checking out all the links given in there for more information, im still left wondering, what the heck is it? im adding alot of different features to my site, so if it is something worth adding, id like to check it out, only...i want to know what it is first :-\

Joomla is an open source CMS, something similar to PHP-Nuke and all the others. It acts as a basic template for a site, with you just filling in the content. There are also extra mods, add-ins and plugins to add extra features or functions to the site, and more themes to download.
This is not really something you would add to a site, but the foundations for an entire website. As you already have a site and are adding features, I would advise you to avoid a CMS, as you don't really need one, unless you are willing to go for a complete redesign.
If you want more information about what Joomla is and does then visit http://www.joomla.org/, or just put the phrase "Powered by Joomla!" into a search engine, and a list of sites running Joomla will appear, so you can see what it is used for. If you are interested then there is a live demo version you can play around with here.

ok, thank you very much. i had seen alot about it around and thought it was something to add onto a site, i didnt realize it was a whole site base. my site is already pretty well formed, so i think ill be avoiding it thanks alot

As mentioned above, Joomla is an open source content management system. It is similar to Mambo (http://www.mamboserver.com/) in that Joomla is a fork of Mambo, and shares similar features. I have seen professionally made sites in both Mambo and Joomla, and I can say that although they aren't nearly as sharp as Microsoft's site, they are still pretty nice.
