My two cents: Don't care either way, as long as mildly off-topic posts are still allowed. All the other forums I go to have off-topic sections (forum for the Gran Turismo series has a section for tv/movies, music, etc.) I actually enjoy seeing what people here have to say on non-model car related topics, and think that it would be too cumbersome and, well, lame to take it to PMs. But hey, if there is another section created, then I have one more section that I get to read!
