Oddmuse is a program to run a wiki. A wiki can be used for communication in a team or for documentation, when things have to be quick and easy: Content Management for everybody.
A wiki enables other people to quickly join efforts. In the office, you can introduce new employees, distribute phone lists, store memos, plan trips, document projects, prepare meetings, or describe internal processes.
For many free software projects wikis have taken an important role somewhere between manual, FAQ, IRC, and mailing lists.
Oddmuse is very easy to install: Simple installation, compact code, and easy extensibility were the most important design factors.
