Welcome Fry! I think maybe my friends would consider me more of a Leela. I exist in order to organize things and make people behave kindly to each other, even if I have to kick and shoot to make them behave correctly!
Please, for the love of all things good and just, DO NOT USE DRM. I promise, it will be a huge marketing advantage over anything Amazon, Sony, etc are doing. They restrict and exclude sales by using proprietary DRM. Just offer DRM-free content and the reading world will beat a path to your bookstore.
