One of the issues I have noticed is that there are too many sub forums. In my opinion, forums are more active and operate better with a minimal amount of sub forums (interior, exterior, meets and drives, etc). They stay more relevant and people crosspost less often. It's also much easier to browse. Obviously, division and separation are still necessary, but I think some consolidation would be useful, especially in the for sale forum, where there are multiple sub forums.
Just something to think about!
