because this is an open source project
you wont have to pay to use it
basically this script lets you manage banners . buttons and text links on your site and the amount of views they get and clicks .. its a total managment script for all outbound links you have on your site and im currently testing it out for use with babesandstuff.com and ill let you know how it goes
it does look extremely promising and ive heard nothing but good stuff about it

great free script
