Well Renderosity has to be the best! It's certainly the most friendly and helpful that I've found. Then CGTalk mentioned by Bryde above, it has a huge number of members who are expert in all areas of modelling animation rendering and any other aspect of CGI you care to mention. Spiraloid should be great, it seems to be where the really great modellers (including Bay Raitt!)hang out. It's been pretty dead for the last six months though, I just hope it picks up again cos I'd love to post there if I ever get good enough! Otherwise it's a great place to lurk if it ever gets active again. Just take a look at the challenges and gallery and then pick your jaw up off the floor! Baz
