The first wave of beta YPN publishers are expecting their first payments for August earnings shortly. The terms state that checks will be sent 45 days after the earnings period, meaning August earnings should be sent by October 15th. Publishers noticed their total balanced decreased a few days ago, by the August earnings amount, but nothing showed up in payment history or available balance when this was done.
I went direct to YPN to get the scoop on payments, since this is the first pay period and publishers aren’t quite sure what to expect. And I can confirm that checks are being sent to publishers this week. YPN is also working on shortening up the 45 days publishers currently wait, so that will be nice to see, especially with AdSense working on 30 days.
So if you met the $100 minimum for August earnings, you should expect to receive your payment very soon.
