I do the Yahoo Pfaff and Babylock fora. Also one of the quilting ones. Mostly just read. They are moderated. Joined the forum at Missouri Quilts. The older Pfaff fora have been around for a long time. Compusew with Jan covers Pfaff and Viking software, and good with Embird. Strictly moderated.
I do Yahoo astronomy and photography, so I have a mess of stuff to read at one go.
