I'll try to answer a number of replies at once.
Thanks, Jon, for offering to do that conversion.
As for other means of getting ebooks out:
I'm still on the learning curve here, but...you could spend a lot of time placing books individually through Amazon (which I don't believe requires exclusive rights, though I'm not positive) and places like fictionwise, which hosts my e-reads books, but where sales have been low. I did not know that Baen had worked with non-Baen writers to sell their ebooks, so that's something I need to check out (thanks for the tip).
I don't know if the Amazon program that lets authors sell directly through them includes formats beyond the Kindle or not. Something else I need to learn.
Thanks for all the replies, everyone! I'm going out for some fresh air.
Jeff
