I was wondering, does anyone know a code or free site where I can know which members of my site/forum referred who? On my site, I give people points if they get trivia/questions right. The points are exchanged for desktops and such. Anyway, I just created a new forum for my site. I wanted to give points to people who referred others to my forum. How do I go about this? Also, are there any free forums that have that feature already?
