Parlez Vous: CMS?
Content Management System (CMS) - This is a computer software/system used to manage a bunch of files (content). It allows you to easily create, manage, edit, and publish your “content” in a consistent manner.

This is very helpful for websites because for the most part, most pages within a site will have the same layout, and so a CMS system can make it very easy to maintain such a site.
Popular CMSs include Joomla, Mambo & PHPNuke.

The drawback with CMSs is that they are not very flexible (or rather, not as flexible as writing/designing a site from the ground up). However with that said, one can achieve a great deal of creativity and flexiblity, within a CMS environment and the open source community for CMS is quite large, so there is always support for instances when you want to push certain CMSs to their limit.
We designed Thisizgame.com using WordPress as the CMS so that it was easy for our client to keep fans updated in a blog centered site, with other pages. We specialize in using Wordpress & Joomla, however we are able to branch into other CMSs and customize them to our clients needs.
