Only one registration per unique email, no double registration.Asked by oynyberg on January 16, 2015 at 04:05 AM
Is it possible to restrict to only register once with the same e-mail?
Best sulution for me:
A members area with password, so they can change their adress if they moves to a new place for example.
If not, do you know anybody who have online forms with membership area?
