So I said I'd post the process for anyone interested in publishing an ebook of their own, to check off their bucket list before they take a hot air balloon ride or whatever. Rumbler might do it differently, this is what I found to be easiest.
Formatting sucks. You'd think it would be easy, it's just text, but there are a thousand things that can go wrong and you're staring at a wall of bold italic.
After much frustration, I just imported everything into OpenOffice. You'll want to click the puzzle piece on the main page, which will take you to their extensions website, and search for Write2ePub. Download and install that extension, and restart OpenOffice. Write or import your story/novel/etc. Use the three buttons to adjust your ePub output settings, add a cover and metadata, etc. and then export.
Now, from there, I use a program called Sigil. It's a WYSIWYG ePub editor. Import the ePub file you created in OpenOffice, and use Sigil for any cleanup (deleting blank pages, etc.). Save the file.

http://calibre-ebook.com/In Calibre you can tweak the metadata info of your book, but more importantly you can convert your book to other formats. If you plan on publishing to Kindle/Amazon, convert to MOBI and select Kindle under page setup. Do your conversion, check the book on the built in ereader, go back and do any tweaking and reformat if necessary.
You also might want to download the Kindle Previewer to see how it's gonna look on an actual Kindle, if you don't own one:
