Hi there, and welcome!
The
Workshop forum is a good place to get technical help for ebook production, although random questions anywhere at Mobileread tend to get answered.
Poke around the forums, check out the wiki, and jump in anywhere.
Flamewar topics: DRM, ebook pricing, piracy, copyright, the-future-of-publishing, Kindle vs. other devices, best ebook format, PDF as ebook format. Which doesn't mean you can't or shouldn't participate in those topics. Just know that they've been argued from many directions many times; the regulars have almost refined them to a form of shorthand. (And there are no conclusions, just occasional new twists on the old arguments.)
