How email address change requests work
There might be the situation where a user wants or needs to change the email
address in django.contrib.auth.models.User. Such a request is handled
considering following rules:
- A user is only allowed one change request at a time.
- If a user unintentionally supplied a wrong email address a pending change
request explicitly needs to be deleted before a new one can be requested. The
user needs to delete the pending request by him- or herself. This is to
prevent administrational issues on projects.
