If you've tried to get to the Mid-Atlantic User Group Portal recently, you may have noticed it's now showing a "parked" domain page. We've had a little hiccup with renewing the domain name. Hopefully, we'll have it remedied soon.
In the meantime, if you're trying to locate a user group in the Mid-Atlantic area, Jeremy Kadlec of the Northern Virginia SQL Server Users Group maintains a good list here.
You can also search for user groups at Codezone.
UPDATE: Removed link to ugmidatlantic.com, as the domain is no longer under my control. If you have linked to this domain in the past, please remove those links from your site. Sorry for any inconvenience.
