Book Oven is shutting down, because we are spending all our time on PressBooks, a fabulous, and simple ebook production tool. If you have a Book Oven account, and have content in there that you'd like to extract, please contact us at: support@pressbooks.com (before December 15, when we'll just have a redirect up here).

One way or another, you should head on over to PressBooks, sign-up, and start making books!
