No, it's not. It's just Michael R, no middle initial. He was using his credit card to make the reservation and you are right, anyone can make a purchase, reservation, what not, in anyone's name. However, there should still be only one user name per email address allowed. On top of that I know his user name AND password now. It's really his own fault by entering a wrong email address in the first place but he shouldn't have been allowed to enter one that is already assigned in the system.
