Here's help for the Indie-publishing author, should it be needed.
At the time I created this book, I had only uploaded to Amazon and B&N online, but have since then also uploaded to Smashwords and Kobo. Get the free e-book online for formatting Smashwords docs. Other than that, the steps you go through for Amazon and B&N will help you feel confident to navigate elsewhere. Best wishes!
