On the weekend of July 13-14, Harvard High-Impact Philanthropy will be hosting a rationalist megameetup. Everyone who can make the trip is strongly encouraged to come. We'll meet at the Harvard Science Center in room B-10 at noon on both days. Crash space is available; comment or send me a PM to arrange. (I am supposed to say "the megameetup is not sponsored by the Science Center or Harvard University.") If you're planning to come, please RSVP in this thread or on our facebook event page.
