A: Sub-forum, and make it a non-repliable archive, or just have the archive deleted. Close the old accounts, and make new ones maybe? Give the forum a less bleak design, maybe in lieu of the new to be released album character (obviously, this would mean waiting until its release). Maybe a 5 strikes and you're out system, if you post here only to whine, or bring people down, if it happens for five consecutive posts you get a days ban or something. Just to be a little militant. And Ragnarok is the war of the gods, in which the world is unmade, then made anew free from its old poisons.
Q: How's that sound?
