Rule 1: Noobs get first dibs on protos. Make sure you state your interest in protos regularly.
Rule 2: Ask questions often. The more common and obvious the question the better. Don't worry if someone else might have already answered your question before and that a simple search would turn up the answer-ask it again. And repeat your question yet again in a different sub-forum if you don't like the first answers.
Rule 3: Everyone loves a clown-especially Rot and members that have been here for several years. Being insulting, quippy and generally annoying is the "secret sauce" of acceptance here.
Rule 4: The subforum categories are more of a guideline than a rule. Just place your post wherever and it'll all sort itself out.
Rule 5: The Marketplace forum caters to wheeler-dealers. After making a big profit reselling something you bought in the Marketplace on EBay, make sure you post details about it here so everyone can marvel at your financial gamesmanship.
Rule 6: Cart reproductions and bootleg items are especially welcome on the Marketplace. All that matters is that the game boots up.
Rule 7: Rot loves PMs. The guy would love nothing better than to answer PMs all day. PM Rot, won't you?
Rule 8: Just because a thread is old doesn't mean that it's not relevant today. Add a little post to the end of that old thread so that all the old-timers can enjoy a welcome reminder of days long passed.
Rule 9: Sarcasm has no place in this forum, and especially not in any rule lists. Rulesmaking is serious business.
