Suprisingly large, well put togther reefin community here. It's slowly becoming an organized movement here also

You'll also want to check out NCFrag, RARE (I think that's the name, Raleigh Area Reef something I think...), CCRK (Coastal Carolina Reef Keepers). We all have message boards and email lists on Yahoo groups and do a little posting on RC.
The new "bigger and better" group is supposed to be MASC, Marine Aquarium Soceity of the Carolinas. I haven't been very involoved in any of the groups lately since I opened up a store about a year ago.
Pretty much all the folks I've had the pleasure of meeting in person from these groups have been extremely good people willing to help out with just about anything. Really good to get involved, get lots of frags that way too
