What is Geeklog? Geeklog is a PHP/MySQL based application for managing dynamic web content.  "Out of the box", it is a blog engine, or a CMS with support for comments, trackbacks, multiple syndication formats, spam protection, and all the other vital features of such a system.

The core Geeklog distribution can easily be extended by the many community developed plugins to radically alter its functionality. Available plugins include forums, image galleries, and many more.
