Word is an excellent tool for writing and creating the final files for self publishing, but many authors don’t take the time to learn even the basics of using this great software. I get manuscripts full of needless multiple formatting with tabs and single spaces that create problems for final formatting. On more than one occasion I’ve had to clear all the formatting so that I could begin again with clean text. One was so problematic that I copied the entire manuscript and pasted into Notepad to wipe all formatting. Then I copied and pasted it onto a new Word file. I suggest using Normal Style for writing and leave the formatting for after all the editing is complete, especially if you aren’t doing the formatting.
