Awwww, thanks Thermal.
The gamer group here in NYC is found through meetup.com, so try that one. Or facebook maybe?
You could always try an internet dating site and mention that you're looking for a gaming buddy/girlfriend in the Atlanta area? Maybe one of those sites like Soulgeek.com where the people have more of a geeky bent.
I met my boyfriend on a dating site, and he's pretty into games as well. In fact, I've had more problems dating guys who WEREN'T gamers, believe it or not.
We joke that the couple that slays together, stays together. ;)
