I think it's a great idea. One Board I was a member of (has been closed for reorganization for 10 months now!) had a separate area for machine quilting discussions. It included both longarm and home machine questions and was used a lot. Not only process questions, but info on set ups, what to look for when machine shopping or looking for someone to do your quilting, pattern info, etc. Very useful indeed. It's certainly worth consideration IMHO.
