If you didn't add your payment details when you signed up, or if you want to change it, you must send a support ticket to update it. Once you add the information, it will stay, so you only have to do it once (unless you change it with another ticket later).
To change payment options, simply use the "Payment Type" dropdown list in your Account settings and select which one you want to use. If all the necessary information is filled in, you will get paid as usual.
To hold the commissions in your account, simply set the "Payment Type" dropdown list to "SELECT". That way we know not to send your money anywhere.
