It just went 'live' this morning. For a day or so, all you could see was the book cover. Now, the book is available. Yey!
I'm still waiting for the book to be set up on Barnes and Noble, Sony, Kobo, Diesel and the Apple iStore. I'm told it's 'pending', meaning only a few days, hopefully.
The key was making sure the formatted book and cover met the standards required, e.g. indenting, pixel width and height for the cover, chapter heading, copyright language, etc. My upload to Smashwords sat in a queue of 595 ahead of mine. It was in that queue from about 9:20am until about 4:30 or 5:00pm that same day. I was thinking it might take five or ten minutes. Not!
