An open source content management system currently in heavy development. Currently in use by Mad Hatter's IMC who are currently coding new modules for better IMC/Open Publishing functionality. Though not meant only for use by IMC sites, it can be used to get a site up and running quickly using its easy, web based, install script.
Even though it was branched from phpuke, it's starting to become a much more robust system. It is available at http://www.postnuke.com and also on Sourceforge.
