I actually think this would be a good idea. Only question: Would religious threads be allowed? I can make a basic outline of the rules right now:
1: Serious discussion only. Any forum games, spam, or anything non-serious will be removed and you will be banned for a week.
2: Don't try to force your views on everyone. (Don't spam "oh imm rite and n0n3 of u r becuz 1m c007!!!!11!!one.")
3: Again, no spam, forum games, youtube links (unless they relate to the discussion) or you will be banned for a week.
