personally i would see the rejection as an opportunity to improve the product so that it is a product the marketplace would want to sell.

would of been a better idea to ask some of the top vendors, like rebelmommy and thorne and the likes, how much of their stuff has been rejected over the years, and what they did to improve said product, and get it in the marketplace, maybe get some info too about what seems to sell well for them and what does not.

that way you get the feedback on how to be a successful vendor, and you don't break the rules by posting private E-mails to the forums.
