'Send an "approval is complete" email to the user associated with this
``SupervisedRegistrationProfile``.
The email will use the following templates,
which can be overriden by settings APPROVAL_COMPLETE_EMAIL_SUBJECT,
APPROVAL_COMPLETE_EMAIL_BODY, and APPROVAL_COMPLETE_EMAIL_HTML appropriately:
``registration/admin_approve_complete_email_subject.txt``
This template will be used for the subject line of the
email. Because it is used as the subject line of an email,
this template\'s output **must** be only a single line of
text; output longer than one line will be forcibly joined
into only a single line.
``registration/admin_approve_complete_email.txt``
This template will be used for the text body of the email.
``registration/admin_approve_complete_email.html``
This template will be used for the text body of the email.
These templates will each receive the following context
variables:
``user``
The new user account
``site``
An object representing the site on which the user
registered; depending on whether ``django.contrib.sites``
is installed, this may be an instance of either
``django.contrib.sites.models.Site`` (if the sites
application is installed) or
``django.contrib.sites.requests.RequestSite`` (if
not). Consult the documentation for the Django sites
framework for details regarding these objects\' interfaces.
``request``
Optional Django\'s ``HttpRequest`` object from view.
If supplied will be passed to the template for better
flexibility via ``RequestContext``.'
