Sorry it's taken me a while to respond: I've been away doing a travel feature for the magazine.
I think it's a huge pity that the Forum is being used for anything but caravanners exchanging information, advice and ideas about caravanning. The best advice I can give at the moment is that users simply ignore any provocative emails from those who are abusing the website - avoid the temptation even to write a couple of words in response, because this will only encourage more behaviour of this sort. If you completely ignore the abusive messages and make sure that you yourselves only write with helpful, positive messages about caravanning, then there's a chance that any troublemakers will give up. As soon as you react to any personal remarks, you encourage more attention-seeking or provocative comments. It will take a bit of self-control not to respond in some cases, but it could work so let's try it. Alex Newby
