Presumably rename one PayPal plugin as 'PayPal-1' and copy the PayPal plugin and rename it PayPal-2. But Why?
Thank you. I was unaware that I could rename and duplicate plugins. Two PayPal accounts- one for the regular fee structure and one for the micropayment fee structure. One can't have both fee structures on the same account.
Cannot think of any other way of achieving what you are thinking. Suggest you submit a support ticket and get definite answer from aMember.
