Our return cookie is is set on the client's machine to expire in 10 years. However, it is important to note that this is a "return cookie" ? cookies are not our primary tracking method ? we allow customers to register free and when they do that, they get uninterrupted free chat. (This is the incentive to the customer that we offer.) Once an affiliate's referred customer is in the registered customer's database, that customer is "owned" by that affiliate, with future rev-share from that customer's purchases paid to the credit of that referring webmaster.
