Toplist is a module that lets webmasters submit their links, have them approved and keep a link exchange that tracks website referrers, thereby giving more exposures to more-active websites.
This module simply implements a system that has been going on for ages on the Internet: automatic link exchanges between related websites that also tracks the amount of visitors sent in, so that a classification of the "top referrers" can be kept. This module does exactly this.
I AM CURRENTLY LOOKING FOR SOMEBODY TO TEST THIS MODULE, MY TESTS ARE NOT EXTENSIVE ENOUGH TO MAKE THIS MODULE READY FOR PRODUCTION SYSTEMS. USE AT YOUR OWN RISK.
