gnu, What are these negative posts you mention?   Everyone here is perfectly well behaved and deeply concerned about their peers, friends and even their enemies.
Even the character Martin Gibson was just an invention by an otherwise well intentioned member.

IF you really see something totally negative it is probably a normal human meltdown which should be forgiven or seen as a cry for help.

I refuse to believe there are people here who would deliberatly cause harm or ill feeling to others.
But there sure the hell are posts that are a waste of time;-)
