You guys, this is so much fun, I can't even tell you. You have to try this! Even if you're still enjoying the whole Agent Search thing, take one of your older novels and toss it up there, at least on Smashwords. (It's totes easy to do. Kindle: not as easy. Smashwords: yeehaw!)
Or write a 1,000 word short story and put it up there for 99 cents, or for free. Just do it because it's fun!! I can't believe I waited this long!
