I have questions on registration with duplicating email.
When i use an email address that's already registered, i am still being directed to "You're Registered" page, without any notice that the email address has already been used before. (But in fact this registration is not recorded)
Later when i check the registration report, i can only refer to the 1st registration record, but the details for other duplicating registrations are not recorded.
This may cause problem if user use the same email to register for the their colleagues and work partners. Is there a way to check email field/ let registrants know the email has already been registered to avoide the confusion?
