I agree with Mike Stackpole on this. Read his article here. http://www.huffingtonpost.com/michael-a-stackpole/borders-bookbrewer-vampir_b_823926.html
Authors should avoid this program at all costs. I saw it when it first arrived, laughed at the stupidity of Borders and the last gasp attempt on their part and then forgot it. But I have heard lately of a few people going with this silliness. Stay away from putting your work there, read Mike’s comments.
