Satellite 2 is going to be a fun-packed weekend, with serious items on stuff like the Apollo guidance computer, panels on the Moon in SF and on Iain M. Banks's work, quizzes, silly games (I believe the ever-popular Finding Uranus is returning!), a disco on the Saturday evening, and of course a dealers' room/art show.
If you haven't joined up yet, why not?
If you have... have you thought about volunteering to help? The con is run by its members, and everyone can contribute. A little light gophering is a good way to meet people and can make the con a lot more fun, especially if it's your first time.
