OK group, the base of a Book Designer Wiki has been started. There is a link to it off the Wiki Conversion Software page or you can get there directly at
https://wiki.mobileread.com/wiki/Book_Designer
Some of it was clipped from posts in MobileRead and there are still many areas that need help. I felt it was better to start it now and let everyone add their own rather than keep it all here and hope I could put everything in at once.
Comments, feedback, and other contributions are always welcome.
