Nyxcite (nyx-cite) is a lightweight, moderately featured discussion forum software based on the Django framework. It is named for the private gaming server it was originally created for. The forum is loosely based off of other Django forum projects (namely beastly and django-forum), but also includes thread watching and notification, bbCode support and straps onto the Django users system.
Right now, the best way to get your hands on this is to grab the latest revision from Subversion:
svn checkout http://nyxcite.googlecode.com/svn/trunk/ nyxcite
