As a premium member you should not and do not need to ping your links manually, that feature of for the free ping service. Your links will be pinged automatically for you when you enter them in your account. You are entitled to whatever number of links according to your package and can change them every 24 hours and they will be pinged automatically.

If you keep the links as they are they will be pinged automatically every three days.
