Thanks for the info and encouragement. Still not sure what my audience looks like. Most of "what comes out" is genre-defying. I am currently working on something I'm trying to finish this week. I'll look more into Dale's tips.
BTW it looks like Draft2Digital does publish work on Amazon.
Yes, D2D DOES publish to Amazon, but I encourage you to go THROUGH Amazon rather than D2D for Kindle and paperback on Amazon...you'll have more control over your books, royalties, and promotional strategies.
