If you click the "Invite friends" tab at the top of the page then in the sub menu just underneath click "referred friends" a list of all your invited friends and their status will appear next to that is a box with the balance of your TaF account.
When this amount reaches, i believe, $50 you can request a cashout to one of the TaF cashout options
