No, I have not. Joe is scaling back his operation, which is why I had to go to CreateSpace/Amazon to do my second book.

I do have another question though. What algorithm or circumstance produces the absurdly    wild prices seen (ocasionally in four figures) on Amazon for some recent paperbacks?

In the case of the SRS books (which never show up at a reasonable price) I believe it is legit, but some of the others are ridiculous.
