I've submitted the request to add the site to our list of user groups, should be live in a few days.
Congrats on getting this together! Exchange & SBS user groups, let us know what we can do for you. I have a bunch of Exchange 2003 trial CDs I can ship your way (you can also download or order your own), if that would be useful. I also have some other giveaways like a few MS Press books for raffles. Email me at kclemson AT microsoft DOT com if you're interested.
