I have an user on my board where he haven't access the forum since a while ago, even before I transfered from vB to Xenforo. Today I received an email from him that he sent through the board contact form. He claimed that he could not remember his password because it was not finding his e-mail in the system. So I checked his profile and there was no e-mail entered for him. How come that user had no e-mail set to his account?
