I think we should keep all three current boards separate, because by combining them into one, it would:
a) Generate confusion
b) Increase load times (for those of us without cable modems :)
c) Encourage the attention-starved people with multiple aliases (alii?) to post more pointless crap
I also don't think we need a 'general general message board' to cover all topics. This is a Mario site, not an 'everything else besides Mario' site. If people want to discuss things completely unrelated to Mario, they can go somewhere else!
On the other hand, a true General message board could act as a trash can where people who would normally take up space on the Mario-related boards could wreak their havoc...
I'm not getting at anyone in particular, and I don't like to be so blunt. I just don't personally enjoy trying to wade through the several useless, pointless and stupid posts that have been popping up as of late...
