I think that this concentration on the use of swear words might rather be missing the point, the odd expletive used to demonstrate a particular point is harmless, however the situation whereby drunken and abusive posts go unchecked is/was the problem, not the odd jaw breaker from Plum.At worst I estimate we would lose 4'ish members and hope to gain 20.
Hoping to gain 20 new members is a pretty optimistic target. Those from Top who want to join already have and there isn't really anyone else. I can't see much to attract 20/30/40 year olds to the site, but we'll see. If you can retain what we've got that would be an impressive achievement.
Out of interest, I support Plum and see no reason for him to be banned, suspended, advised or anything else really, what do others think.
