Rick, just pay someone else to rework the book, it deserves it! If publishers are too much of a hassle then self publish and give it away as an e-book for free or cheap.

How about instead of them calling you you put "Subscribe to our monthly newsletter" And make it clear this is packed with relevant bargains and insider tips etc etc"
The newsletter would give you lots of valuable e-mail addresses and keep the lines open between you and your audience. It could appeal to people who don't have the time or the inclination to visit the forums.
