Thanks for your reply and your welcome wishes! I will take a look at the Workshop, thanks.
Truth being told I can't stand writing in HTML. I understand the logic behind your reply (I think) -- to use HTML because it does the job as a markup language. But consider that when I have to convert client documents to html, I've got to sit and append <p> </p> to every paragraph, and <h1>, <h2), etc. to the headers and section titles. And while I positively use CSS to manage the formatting of included images and multimedia, HTML would be a big pain for my 300+ page work. And forget trying to have the client save their document in "HTML" from word -- the results are messy so that why I put HTML in quotes.
To answer your question, the final result is going to probably be some kind of technical workbook that I will publish myself (to a very specific niche audience) and then probably add an eBook version.
So Word is great for now in getting everything down and editing (try paginating copying and pasting tons of paragraphs in HTML -- you'd better LOVE the clipboard), it's just that when I'm ready to roll it off the presses, I want it to have a consistent, styled, and professional feel to it.
I've already written an free eBook in Word (you professional guys here would probably consider it an "eBlurb" as it's only 16 pages) in Word as a trial run -- it's an ebook about
organizing your digital photography collection. It was easy to put together and convert to PDF, but since I'm giving it away for free, I don't really care about security and getting paid, etc. It was really a proof of concept for me, but as it's short I really didn't need to start making a really big style guide. So that's why I'm trying now to learn how the pro's do it.
Thanks again for your help.
