All of my paragraphs are indented, but when I upload them, most of them aren't. I am so confused! I'm uploading a word document and I use the tab key... is it a formatting issue in the document? How do most people achieve indented paragraphs? Thanks for any help! 
Don't use the tab key. Ideally you should format your whole document in Word using indents from the document/format menu or whatever. That's a must for ebooks but here one or two spaces should suffice. I'd suggest cutting and pasting into a rich text format using another application (I use TextEdit on a Mac but there's a Notepad or some such in Windows). You can upload a RTF file here. But get rid of the tabs. Nasty habit.
