For whatever reason, I can't copy and paste the link to refer people. So that eliminates trying to refer people I'm playing poker with but don't actually know. On top of that, the two people I have referred I helped fill out the registration, made sure they put my name in correctly, but they didn't automatically show up under friends referred. I still had to pm Zab to get credit. But after all that, neither of them actually did anything with the site. I know one just doesn't have time with his job, but I'm not sure why the other one isn't active. I think you need something to hook people when they do signup. A free opt in or Carbon ticket would go a long way in showing someone how valuable this site can be. If you don't want to give that out, then maybe give us the option of opting in a friend that we referred or transferring them a Carbon coupon.
