I have been to a few and a lot of them surely do not like newbies, they ignored most of my posts or one totally shut me down because of a "misunderstanding" of my posts, the moderator even slandered me by earasing my thread and saying all this bad stuff about me. That has left a bad taste in my mouth and for a while I did not want to join anymore. People seem to think that they are the only way to think and heaven forbid there are any other opinions out there. Personal attacks and such should not be aired out for all to see. Also trolling, which I do not hear about much anymore, was a big problem. I really was fed up with a lot of boards during Stratovarius's drama in the begining of last year, that was such a mess and I almost never posted here or anywhere again. I do belong to another board but that one has been taken over by some people who seem to use it as a chat room and there is not much discussion going on anymore. I really like that band and they actually post regularly, we had some fun during the hockey championships this past summer but then it was no longer any fun. you would always see the same 3 people posting all over the place.
Metalmaiden belongs to other boards and she has had much better sucess than I and I do know that there are some other very good forums out there.
