A while ago, some posters mentioned that it would be good if LW had a forum. Earlier this week I was planning a role-playing game with some other users and decided that a forum would be a good place for us and other groups to play online. And the Less Wrong Forum was born.
Currently, the forum has three boards: Gaming, Less Wrong/SIAI Related Topics, and General/Meta. The Gaming board is for RPGs, Diplomacy, Zendo, or any other games rationalists might enjoy playing together. The LW/SIAI board is for discussing any of the topics we normally discuss on Less Wrong. The General/Meta board is for random topics and discussions of the LW site or the forum itself.
EDIT: Looks like a supermajority of commenters don't want the LW board to exist because it would be redundant with the discussion section. I'll leave it up for a bit longer, and take it down if nobody says they support it.
I encourage everyone to check out the forum and help make it a fun and useful part of the online rationalist community. Please make suggestions in the comments (or on the forum itself!) about how it can be improved.
EDIT: Due to problems with trolls, registration now requires an invite. If you want an account, say so in the comments and I or the other admin (Armok_GoB) will get you one.
The forums are not doing anything right now. What it'll do once it actually develops into somehting at all remains to be seen, but presumably it'll be either somehting different or not at all because if you post a discussion section type of thing you'll want as many people as possible seeing it and thus post it in the discussion section for traffic.
