Thanks for the info. We're not thinking about direct sales to end-users, but also not to universities (who typically don't really care how easy or hard it is for their students to pass the exam, even though there are some image-licensing opportunities with universities... but that's not the main focus). We are hoping to reach medical student associations and offer some opportunity for affiliate programs. We've had some success with those, even though in all cases so far we were the ones contacted by those associations. We think those have the best reach to students in our niche market. A good sales person could find their way to reach those targets. Or that's the hope anyway. In any case, thanks again for the advice, and we'll look up the info and might take you on your offer.
