Well it seems that at last the WordPress users have gathered into the AtlantaWordPress UserGroup. Looks like they're looking for a new meeting location, a bit closer to town. Anybody who knows of a good spot, please drop them a note. As to their charter: according to their meetup:
For web beginners and WP Gurus to get together to learn and bounce ideas off each other, and have a good time!
Meet other local WordPress users, the Web's fastest growing dynamic content management system. Gather and discuss the best ways to work with your WordPress and your site.
Open to anyone interested in learning more about HTML, starting a blog, building your own site and learning about plugin tools to enhance your site.
There's now also a Northwest offshoot as well.
