Earlier today I sent a note to Smashwords that the web page on Barnes and Noble did not have my cover image. I found this disheartening, although the section "People who bought this also bought..." did give me hope that I must have sold something. That being true, imagine what having the book's cover loaded would do.
I received an e-mail back from Mark Coker to waint until Monday as it takes time, and if nothing appears by then to let him know. So that is the plan. Here is the link if you want to check it out, although perhaps the problem will be resolved by then.
