nologic, right on the mark again. The problems (at least as far as the boards that I visit) were with flame wars and inappropriate posts, not topics posted in the wrong forum. And a good many, if not most, of those problems were, IMHO, a direct result of one very prolific poster by the name of ozstamps, who has long since been banished. (BTW, I never did understand all the attempts at secrecy on this board. No sense beating around the bush.)
The issue with moderators is not if, but how.
