Due to a recent change to Giza's Account at Paypal, the current membership signup buttons are not operational. Thanks for those who contacted Giza Support about this. New buttons are being generated ( these are a bit more complex than standard paypal buttons, due to our membership system) and we expect a resolution within 24 hrs, barring the unforseen. We will update here when the new buttons are in place. To our knowledge this has no effect on existing members.
