Two questions on covers:
First, I'm trying to change one word on the back cover text. How do I do that?
Second, are there any tutorials on how to use the cover wizard? I have words running into pictures and words overlapping each other.
To change words on the cover you'll have to go "my projects' and click on the book link where it says revise. Just click through each page until you get to the cover wizard then retype whatever needs changing. There are different themes you see at the top of the page. Each one of those have templates. Some allow you to add one picture and text. Others allow one picture at the top and one at the bottom with text in the middle. I don't know what picture you're using so I can't advise on which to use. You'll have to experiment with it. Also there is a video on youtube https://www.youtube.com/watch?v=xoMxTo9ssJ8 here that shows how to make a cover using the wizard. Hope this helps
