There is new question and answer site writing.codidact.com that is receiving the attention of SE contributors.
There is a lot of good content here at books.se and after asking on their meta. I was able to confirm that they will accept posts from here that fit their scope:
- How can I create a .pdf from a .epub file?
- How can I export text from a .epub file?
- What image formats can I embed in a XYZ file? (where XYZ is an ebook format)
- What are the pros and cons of publishing in XYZ format versus ABC format?
- What tools do I need to edit a XYZ file? (where XYZ is an ebook format)
- Is there any software that will create an ebook from a Wordpress site?
- Can I restrict an ebook so that it can only be read on certain devices?
All fine at writing.codidact.
- I bought an ebook from _____. How can I read it on my Kindle/Nook/iOS device/etc.?
- Why doesn't my Kindle/Nook/ereader show cover images?
Off-topic at writing.codidact. But if you want to ask from the publishing side (supporting other platforms, making sure your images show up), that would be on-topic.
