Are you the same Larry Feldman on NPR, just by chance?
Thanks for all your advice. It is all very sound and I'll see what I can follow of it. The idea of getting the sign up right away is good (I have a window sign being made, but the banner sign got too expensive, but maybe I have to rethink that).
The patience thing is a definate, it is more the logistics of the small class viewing. Robert had the suggestion of the demo, which will be happening, and I think that will help. I'll take your suggestion and try and correlate a press release with the demo (now, where do I put the people who watch, we are only a 400 square foot mat!).
