Each visitor sent to this site via your referral code will be counted. Users with the most referrals during the current month are listed in a "top referrers" list on the left side of the front page of this site. This provides a much more prominent link and more users than a traditional exchange of reciprocal links.
One point is awarded to each user's account for each referral. Another point is awared for referrals during the current month.
All you have to do is get your referral code and post it on your web site.
