Pcwiki

Pcwiki is the ProgClub Wiki software. That's the software that drives the web-site you're looking at. It's a fork of MediaWiki 1.17.0, with a custom theme called OldSkool, and the NoTitle extension. Pcwiki has also been updated to include a link to the W3C HTML validation service at the bottom of every page, boasting HTML5 support.

The code for pcwiki is publicly available from svn:
