KL,
Moodle is sort of like a CMS for school curriculums, etc. I had a chance to chat to the creator (who lives in Perth) the other day. Turns out they control a _majority_ of the market share for this kind of thing world-wide, outdoing pro stuff like WebCT.
Way cool. Please let the creator know that at least some of the PostgreSQL PR network is at his disposal if he wants to attract press to his project.
