I have been having a lot of fun playing around with Drupal (www.leskern.net), and am impressed with it's ease of use, extensibility and of course its cost. I was wondering (in order to satisfy my curiosity and feed my hobby of "messing around") whether there is another open source content management system out there anyone has had experience with. I have also played with Moodle for the place I work, and that, while somewhat tough to install and manage, is pretty nice for education. Thanks. Oh, and I also purchased vBulletin, what MacRumours uses. and something called ImageFolio.
