There is a Silverlight meetup forming in Atlanta, more information is at their website: http://www.meetup.com/The-Atlanta-Silverlight-Meetup-Group/

The group anticipates being able to focus on designer and developer topics centered around creating interactive user experiences via RIAs using Silverlight and tools like Expression Blend.

This is a good opportunity to influence the direction of a fledgling user group focused on an exciting technology! Whether you’re a .NETter getting into design, a Flash designer looking to branch out, or just curious about Silverlight, you’re welcome to join in.

Right now, the meetup is targeted to have an event on April 21, more information will be made available once a venue is selected.
