I will have to look into that. That would be a good solution for online vendors to link over. Does that also indicate when a new member signs up and gives credit? Could this be integrated with the manage vendor area/VendorCP for easy, all in one place, tracking?

When I first posted above I was just thinking about using the vB existing referral system along with something like the referral mod I am running on my site but have it display and make custom querries per vendor within the manage vendor/vendor CP area. I have a lot of brick and mortor sponsors that hand my cards out at their shop. I think it would be a good way to encourage that sort of thing to give them discounts on advertising. But also need a way for me to be able to manage it without creating a bunch of extra steps.
