I can tell you a very simplified version of what happened. The management let one very industrious member repeatedly troll and flame basically the entire board over a very long period of time. Well, monkey see, monkey do.
I never bothered to try and catch up on why SW left, probably eventually decided that life was too short to spend so much time online (especially given the level of frustration he had dealing with the atmosphere).
Read on another forum: "If someone held a gun to my head and said, "You have to move to Salida tomorrow", I'd probably do it. If they told me I had to go to Breckenridge instead, I think I'd just let them pull the trigger."
