There are so many good questions Nick… I also had more. Monthly minimums and such. I just didn’t want to go offtopic, but maybe I should have made something more general…
We have another reply, and I’m calling it a day. Today I’m stopping work earlier. It’s friday night, and I’m taking the night off

1) Do you carry over negative balance?
Yes we do carry over negatives, however we will clear negatives on a monthly basis should you have brought in at least 20 depositing players in the previous month.
2) Is the winning player removed from the account?
We will remove a winning player on a case by case basis only if the affiliate agrees to remove this player as this player can start loosing in the future. Should the player have been removed then no future commissions can be earned either.
3) The webmaster has to request a non negative carry over agreement?
Unsure what you are getting at here, but see point 1.
4) Any restriction?
See point 1.
