Anybody know where I can get a referral mod?

I need a referral mod for ipb 1.3.1 it just needs to give you a link like site.com/?r=username or whatever and keep track of how many you have nothing complex..

I know people think ipb 1.3.1 is not "secure" but I patched it and did some of my own things like htaccess password protected the admincp and some other stuff to make sure it wont get hacked by a script kiddie so please don't tell me to upgrade lol..
