There is a Yahoo discussion group for people who plan on attending the 2008 AG in Denver. People are posting their ideas, holding discussions, offering suggestions, making plans, and getting to know each other a little online before we will actually be meeting in person. (Great for introverts like me) There is a link for roommate matching and you can get in on the ground floor discussions, help plan things, find out what's in the works, and get to know some of the people involved.
I'm looking forward to the AG, meeting new people, and enjoying the programs and events. It's been a long time since I attended an AG (or even an RG, for that matter!) so being able to participate in the party of the year is something I really look forward to!
