The Atlanta board is certainly not extremely active, but I wouldn't say "All post soooo old" (sic). Is there some specific information you are looking for? Do you live in Atlanta? If so, perhaps you can help increase traffic by posting about your experiences!
Well, expecting a reply within a couple of hours on a fairly esoteric question is probably expecting too much, on the ATL board. If you look at the dates of the posts, you will see that there are frequently several days between posts.
