I'm astonished by this guy. He has gone well beyond making a nuisance of himself. I feel very sorry for the moderators who are having to put up with this rubbish. Does he have personal issues with someone involved with this site? It seems to me that he has passed a line and is displaying some truly mentally disturbed behaviour. I'm serious - he sounds like a guy who could be a danger to others.
Anyway, here's hoping he tires of such infantile behaviour...
