I like that one Alexandra mentioned and there is another one called Redtailboas.net that's also pretty good. Be prepared for that one though (the .net one, lol) - the folks there are a little more fanatical about maintaining pure locality bloodlines. But it seems to be a good group over all and is quite informative.
Careful, I belong to redtailboa.net. lol
