www.vfxtalk.com (http://www.vfxtalk.com) is a (relatively) new online Compositing Community.
There seemed to be a lack of online community solely dedicated to compositors, so we set up VFXTalk (http://www.vfxtalk.com) to fill this gap. Since the launch on 1st February, we have been growing steadily, and have a large number of professional compositors involved.
If you're interested in compositing at all, it would be great to see you over there... The URL again? www.vfxtalk.com (http://www.vfxtalk.com)
