About 30 seconds in the FAQ and I found this:
Quote: "Account balances are paid monthly in full within 15 days of the end of the month. If you would like to have your checks withheld until you reach a certain dollar amount (to offset check cashing fees), you can set this with your other payment info in the Payment Info form. Payment through PayPal is also an option."
Apparently there is a "Payment Info" form when you are logged in, and they pay you monthly with either a check or paypal (your choice). Or at least that's what I can make of it. Hope that helps
