I´m using magento as POS for travel services, so the user only fills in the “customer create account” and my sale people finish the sale from backend. Since sometimes we have a family traveling toguether but all contracts (for legal purposes) are individual, however most times one person is responsible for filling in the form (I´m using create account page for that) and paying, I have the same email for 2 or more customers. And here is the problem, since magento does not allow to create 2 accounts with same email. Does anyone have an idea on how to allow it to create different accounts with email address? (remember, I don´t allow customers to login to the system so it´s not a problem future password retrieve or login attempts).

Thanks in advance!
