Trolling is where people are harassed online. The old Forum, which had been going a lot longer than this one has, was taken down by its owner for reasons best known to herself. That's all I want to say about that, except to say that she refused all offers of help and an offer from me and probably others too to take it over, including the costs of running it.
I'm going to lock this thread now, because it's a subject which has been gone over ad nauseum elsewhere.
