I’ve been playing with Joomla this weekend. We’ve always built our own CMS but I finally gave in and tried Joomla. It’s a very robust CMS and widely used. It’s a little slow when setting up, but it does make creating a manageable web site fairly easy. They have lots of plugins to do just about anything you want to do. If you’re a novice, or an expert who wants to get something up and running quickly, give it a try.
