def METHOD_NAME(self, request, **kwargs):
    """
    Given a username, email address and password, register a new
    user account, which will initially be inactive.
    Along with the new ``User`` object, a new
    ``registration.models.RegistrationProfile`` will be created,
    tied to that ``User``, containing the activation key which
    will be used for this account.
    An email will be sent to the supplied email address; this
    email should contain an activation link. The email will be
    rendered using two templates. See the documentation for
    ``RegistrationProfile.send_activation_email()`` for
    information about these templates and the contexts provided to
    them.
    After the ``User`` and ``RegistrationProfile`` are created and
    the activation email is sent, the signal
    ``registration.signals.user_registered`` will be sent, with
    the new ``User`` as the keyword argument ``user`` and the
    class of this backend as the sender.
