Slightly off topic but If you look into phpBB you can set different styles for each forum if you wanted to go that route. You'd only need to maintain custom css file for each subsection even if it were some as simple as different image headers. On the backend it's all the same forum but on the front end you could create the illusion of separate forums since they would be visually different.
