jimmy3way, once you get to the signup page, the referral code has already been recorded on your behalf by the stats, so that if the surfer subscribes leaving the checkbox for the other "5 days free" unchecked, you get the credit, if he checks it, you also get the credit while, he gets access to the TB site plus 5 days free to another site, so that TB and the other site can make money if he stays member beyond the 5 day free trial.
I don't know what you are saying about AVS traffic, since TB has nothing to do with AVS traffic, or at least for me. If anyone delivers AVS traffic to a paysite, it's his problem how he manages to convert it. But the fact is, as far as I can see, that you get the credit whether the surfer checks or leaves unchecked the checkbox for 5 days free, it's just an option for TB to make more money out of a surfer, and it's not compulsory for him. I see there is no way for him to subscribe only to the % days free, and not to TB, so that affiliates don't get credit.
Lenny2, I saw the checkbox option for both direct site, or affiliate (code) site.
I guess Alli will make it clearer Monday morning.
