There are a number of different LUGs around the Atlanta Metro area.
* ALE - - Atlanta Linux Enthusiasts - sign up the the email listsrv to stay in contact.
* ALE-NW - - Marietta area ALE chapter. Meets monthly at SPSU.
* GA-400 Linux Group - - Meets informally every Sunday afternoon. Perfect for non-pros to learn more.
* GA-Tech LUG - Georgia Tech University
* Newnan LUG - - also called the South Atlanta LUG - seems active in OpenStack and OpenvSwitch stuff.
and a few others that I don't know personally The North East area has had a few attempts to get started.

Anyway, just wanted to make it clear that these LUGs are Ubuntu friendly and invite everyone.
