Boat class attack: If it´s part of the culture, what's the point in hiding it. Better allow the discussion activity to have it documented, so readers can make informed decisions, either about the issues under discussion or about their belonging to the cat sailing culture.

Personal attacks. I don't remember reading them, but if they are not in the context of sailing discussion, a good thing is to move them out to a separated cathegory (Offtopic, miscelaneous discussion, etc.) Telemarktips.com, for those who know it, has a specific section for that, they used to describe it as a section not present there for the interest of off topic discussion but to be able to separate it from the discussion around the subjetc. Now they changed that description I think, but I guess the idea is the same. But I've heard of forums where online aggressivity between members has moved to real life and the forum has been in involved in legal troubles, I don't have any detail, just heard about it, but its something to be aware of I think.
