Progress report
I came home to...discover that CreateSpace had sent my proof to my old address (boy, it HAS been a long time since I've done a book, hasn't it!). I have now updated my shipping address with them, and hopefully it will come before long.
Tax stuff is pretty much wrapped up, with some exceptions that I'm sure will blow up in my face with delightful unpredictability over the next two months. In any case, it looks like I should be able to start working on the e-book fairly soon.
