# *** NOTE ***
# As the site uses email instead of username, I'm changing how a User object
# displays or identifies itself in admin. The default in Django (file is
# lib/python2.7/site-packages/django/contrib/auth/models.py) is
#
#    def __str__(self):
#        return self.get_username()
#
#    def natural_key(self):
#        return (self.get_username(),)
#
# I'm overriding that a cheap way. I'm not sure if I should replace the entire
# User object ... might be better.
