Lets say I have 2 e-mails added to my moneybookers account. If someone pay me twice, first on the first e-mail and the second time on the other e-mail, can he somehow know that he is paying the same person? I am asking this because we had discussion with my friend and he says he cant know.
You have the option to make your additional email either "Primary" or "Disable". When you make it primary it is same as he is sending to your original email address (With which you registered at Money bookers). And I doubt that someone could know that he is paying you if you ask him to pay to the new email because it doesn't show your name any where.
