It is working fine on my site. I used the id 2 from another user and it input that person's name in the referrer box on a new registration. If you click your own link, yes it will show up as you. Try using another referred id on the end of it after you log out and you will see that person's name in the referrer box on a new registration. if you still are having problems figuring it out, PM me and we will go to IM and get it taken care of.
