As a forum operator myself I would like to support the Malcolm's statement.
Most of the people who use the forums which I am involved with are responsible adults who indulge in deep and meaningful discussion in addition to banter which can sometimes get near the knuckle. These discussions are only spoilt by the occasional 'idiot' (insert your own phrase) who lacks the imagination to discuss a topic in an acceptable manner and resorts to personal insult out of sheer frustration. The more responsible members are usually quick to report such behaviour and offensive posts are automatically removed from view if they are flagged a certain number of times.
I am going to remain open minded about this forum until after this years TT and then decide whether to continue calling in. I will not be able to make it to the TT this year so I will be reliant on the forum, Manx Radio and hopefully ITV4's coverage of the event, for my TT fix.
