Give me a few days and i'll see if i can come up with a simple mockup/proof of concept (nothing too fancy). I should be able to get a very basic forum plus a simple wiki¹ going (hey, gotta put those list of links and FAQs somewhere).

¹ i have a wiki in some project of mine, should be easy enough to pull the database schema and configs into a new project. The forum part will use the same editor and renderer, anyway
