I recently added Upload to the Goodreads database (which was a cinch -- thanks to Goodreads to making it so easy!), and when I was reviewing the Upload book page I noticed that one of the more prominent booksellers on Goodreads is Kobo, a self-publishing service I hadn't heard of. After doing a bit of research, I concluded that Kobo is very indie-friendly, so I signed up for an account and went through the steps of their very user-friendly interface to publish Upload. It should be available for download within the next few days.
