General music discussion (this board), chat, pop culture, non-metal, Trade, Opeth & sometimes The Iron Maidens.
I also post a little on Roadrunner's In the Pit, but it's very rarely I do that anymore, as it's been flooded with stupid & uninteresting posts like "Is anybody here? I'm bored", "Warboy is a faggot" (or feggot as it's called there) and shit like that. There's also so many threads that if you post something and you come back the next day to see if anybody has replied it's in page 15 or something. There's not a search engine, so it's hard to find it again.
I also post a little on a Danish page called Rapspot. It was a page I posted a lot on when I listened to hip hop around 4 years ago, but I don't post that much there anymore. Maybe a little out of loyalty and if there's a discussion that I can participate in (talking about sampling, old music, mp3's and shit like that).
