In cases where someone does not have an email address like an adolescent, an adult may register that user after logging out but if that adult puts their email address in the field, the app will say that the user is already registered and so should register him/herself after login but that's not the correct thing to do..
One choice is to just not check if the user is already registered and continue with the anonymous registration. That's the simplest thing to do. Maybe we should add a check like, I'm registering someone else who doesn't have an account.
