Is there an "All of the above" option?
Anyway, I know this sort of thing all too well. There was a forum run by a narcissistic, power-hungry moron, but the other people (even the mods) were alright, and even the forum itself was decent enough. This guy would ban people for, among other meaningless reasons, simply being registered to (what he thought was) a rival forum, myself included. Over the years, the forum continued on with relatively little trouble. Then one day, for no apparent reason, he decided to make the forum fee-based.
The forum died that day, and with few exceptions, the comments about it were all glad that it was gone.
