How about putting in a Shake section in the compositing forum? I was redfaced the other day when an industry friend asked me "Do you know of any onlione forums for Shake?"
Without knowing for sure, I confidently directed him to CGTalk. He came back to me an hour later with "Um...they don't have one."
I looked, and it mentions Shake on the main page, in the description of the Compositing forum, but when you open the thread, you only see sections for Digital Fusion, After Effects, and Discreet products.
How 'bout it?
