We run a PPC search engine and have added a pop affilate program. we have a popup script that the affiliate only has to put one link of code in there page, that has aff username and keyword. What we need is for you to modify it so that instead of being a popup it is a popunder and to make it only load once in 24 hours for a user. You need to make these changes to this sciript and not to the code that we give to the affiliates. this should be rather simple i would asume.
