I tried buying a rank but there was no paypal there on the home page for donate it has paypal but when I checkout paypal is not there not I cant buy a rank
It is under "2checkout" You have to register your PayPal through that. Let me know if that's not correct
You can use paypal after the billing page of 2checkout, we have done this because we had to many fraud issues with paypal and 2checkout makes it so it is much safer for us and you to do donate, with 2checkout they fraud check every payment so we don't get it fees in the future which in the past have added up to an awful lot.
