Don't know if you'd count this as a user group or not. I guess so, but not in the traditional monthly-meeting sense. It's a website that tries to coordinate the Ubuntu community in Georgia. They recently co-sponsored an installfest with ALE. They have a mailing list, IRC channel, etc.
From their page at: http://ubuntu-georgia.org
- Create one main place where users will be able to gather and share information about the distribution.
- Plan organized activities to socialize with the group and promote Ubuntu. These events will probably be coordinated closely with LUGs in Georgia; while LUGs include non-Ubuntu users, many promote Ubuntu heavily, and are interested in working with the LoCo group on events. Events which both groups participate in will be general linux-friendly events, with a focus on the use of Ubuntu.
