PAX Twitterers! We have an offline site set up with an event calendar, maps, photos and all that, so that we can coordinate meetups and our evil plans to rule the world!
Head over to http://twitterpax.ning.com/

p.s.: I mean the PAX Twitter User Group fan site is up. If you're not already on Twitter, go sign up and make friends with the other 70 or so members!
