I just got an e-mail from PublishAmerica informing me that my book had no sales in the last six months. Which isn't really surprising, as I did what the Brokeback Mountain guys were unable to do and quit them about five years ago. I double-checked their website and neither my name nor the title of my book show any results, so it doesn't look like they're trying to sell it. Should I chalk this up to their standard ineptitude or is this something I need to be concerned about?
