Hi,
Thanks for the welcome!
Yeah, I'll look at the Open Office route. But I'd really like to keep using my current editor and using it to clean out the typesetting commands etc. by using it's search and replace routines. Then dumping this into Sigil and saving as an epub book.
Regarding my statement about epub not presenting as well as PDF or, indeed, the printed page. I was referring to aesthetics. Which I now realize is silly given what we're trying to do with ebooks. So I should just think of it as supplying words and spaces in as tidy, and compliant (W3), a way as possible.
