Thanks, Adoby. I was afraid of that. lol
I was hoping Calibre had a switch for it, or maybe Sigil would. (I haven't installed Sigil, but would if it would help.)
Anyway, I'll go try the second way first, and if it's too tedious, I'll go for the first.
- edit - Ack. I don't see HTML as an option to convert to.
