Less Wrong will be having a meetup on Saturday at 7pm UTC (convert to other time zones), in the #lesswrong IRC channel on Freenode. If all goes well, this will be a recurring event. If you haven't used IRC before, Mibbit provides a web-based client you can use.
We may do some Paranoid Debating. Discuss rules and procedures here. A few people should bring questions, but avoid looking at the answers if you can avoid it. Depending how many people show up, we'll may need to break into multiple groups. Once we've finalized the rules and done it a few times, I (or someone else) can write a bot to assign roles and keep score.
(Edit: Downgraded Paranoid Debating from being the purpose of the meetup to being a likely activity.)
