1) There is no way to properly input Skrill payment details because when you select Skrill it is asking you for your "player's email". Then when you generate an invoice it looks as if you chose "player account" as a payment method.

2) You can generate and download an invoice but to whom should it be sent. And when?

3) Last but not least on the generated invoice I saw that they are paying me 20% commission. I registered on their affiliate program from a promotional email promising me 50%. But even if they don't honor their promotion everywhere on their site it is advertise 25% not 20%.
