No Max, anonymous guests didn't fuck up anything. Your double standard of acceptable behavior, one for members and one for guests, is what has fucked this place up. Your two-tiered log-in which privleges members above guests fucked it up.Maybe you wouldn't have the problems you have if *you* treated everyone fairly, instead of just your members.
I've said this before. Mudcat is one of several folk music forums/lists I frequent. I don't really care whether it is here tomorrow, and I don't mean that maliciously. Keeping free internet discussion forums afloat is just very low on my priority list in life.
If you aren't going to do anything about the rude and obnoxious behavior of your members, which is all too often at the expense of your guests, then your forum deserves to fail.
