There is one: irc.quakenet.org #opeth, I'm an op there. Say hi to me when you're there.
Well I sent a pm to Opeth.com too, I hope it will make a difference.
Although I respect Moonlapse very much, I DO think this board needs some clearing up. There are way too many abusive posts here. Some said before that's not a bad thing and that it's fun. For them, it might be true. However, on the other side of the medal, many people are not checking in anymore because of this abuse.
I like to think of Opeth fans as intelligent people. It doesn't show on the board...
