In this thread on Forum Rules, we revised and revamped the rules for Cafe Society. While there are some general rules that apply to all of the Straight Dope Message Boards, there are different refinements and different guidelines that apply in different forums.
Please, read the new Rules.
I particularly want to call your attention to the section on resurrecting old threads, which is now more permissive in Cafe Society:
I haven’t been around here very long, but I think this is an excellent policy change! I hope it works out – I know that things can get tricky when they’re allowed “sometimes,” but hopefully we’ll live up to the trust we’ve been given.
Well… it’s basically up to the moderators of each forum. There’s pretty sound reason why, for instance, the moderators of the Pit don’t want people re-opening old scabs. “Oh, look, I see that two years ago there was a great huge bit of excitement about a banned member, what was all that about?”
