There are a few boards where people generally are civil, and also a few 'feel good' boards where everyone is nice to everyone all the time, albeit the discussions on such boards tends to be tepid. Volconvo has a fairly civil forum with in pretty good depth discussions. Yuku runs a feel' good' board, and other boards, too, but I have not found a really lively board on Yuku. The good boards on Yuku tend to have a small number of posters.
