PostNuke is a free, open source content management system forked from PHP-Nuke, released under the GNU General Public License.

Currently PostNuke can provide RSS feeds, internet forums (through PNphpBB2, pnForum and other forums), polls, language internationalization, galleries, chat, e-commerce, games, reviews, links, as well as countless other features with various hooks and modules, many of which are free. PostNuke is also themeable using several theme engines such as Xanthia and Autotheme (also known as AT, or AT-lite), as well as PostNuke's native theming system. Both Xanthia and AutoTheme offer page caching to speed up page generation times. PostNuke is written in PHP and stores its data in a MySQL database. Future versions will work with any database supported by the ADOdb driver. PostNuke will run on any platform that PHP will run on, including with the Apache and IIS webservers.

We install PostNuke on any PHP 4.1+ enabled web server running on Linux, Solaris, BSD, Mac OS X, and Microsoft Windows? platforms which have Apache Web with PHP extension server and MySQL database server installed. You may also request an installation of other versions of Nuke here. Your PostNuke will be set up and configured properly.
