I am a member of NAPP (National Association of Photoshop Professionals) and we have similar things to what you're looking for. There is a yearly membership ($99) involved but if you use Photoshop in a larger capacity than the basic "hobby" mode, it may be someting to look into.

The web address is <www.photoshopuser.com>

It is more "focused" on Photoshop (but that's expected) than your basic 2D type community, but it is a great additional resource.
