I think Comm. Proj. could collapse back into Off-Topic. Although someone with decent knowledge about how to run a CYOA or forum game could technically save the section from the hell to which it has gone.
Mod. Disc. and Gen. Mod. Help could merge.
Drama should fall back to the OT category. As it is it seems to just be a forum that exists so that Badspot can showcase idiots complaining about crap rather than deleting the posts.
You could probably merge all AoT discussion into one forum, but I think that it might just be a waste of effort.
In my own experiences with an Art board, it NEEDS to be general, on DRLFF I created(at least I think I was responsible for it) an art board for stuff related to CC, and it's become inundated with random stuff. There's a reasonable number of such threads around here, but the CYOA and other such threads would still fall under the Off-Topic forum.
One thing I notice is that there are no subforums on OBL, I don't know if this is by preference coincidence or technical limitations, but subforums could be used for several of the above mentioned forums.
