You're right. I didn't click the link before. Now I found the link given by moneymoney and clicked it. But can we access it from somewhere around the forum? Maybe from our Control Panel there? Or some place else? In MMK, there is a shortcut to that page, but there are no referrer page shortcuts in MyHYIP and WTH forum. Do you know about it?
I don't know how to access through forum links. But as poor said, I directly tried to open it by the link below and I could open. Now the higher referrer is indieover with 12 referrals. I think Indieover is going to win the first prize of the referral contest.

Here is the link : http://forum.myhyip.com/referrers.php
