[Answered ]-Why does password reset works with unregistered email in django?

I presume the problem is that your development environment isn’t set up to send emails? In that case, add this in your settings_local(or equivalent):

EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'

This will cause emails to be displayed in the runserver terminal. You can copy-paste any links from there.

That is deliberate, to not-allow outside users to poke at the registration form and see whether a particular email has been registered or not. A “privacy feature”, I guess we could call it.

POST-ing to the same URL is a standard practice in Django. It is not a requirement, but it just makes sense to do that. It makes sense because that way a single View handles both creating of the Form and receiving the data, see Using a form in a view
And the redirection happens from the View, deliberately:

def form_valid(self, request, form):

    # blah blah...

    return redirect(success_url)

The redirection after a POST is also a standard practice, and not just in Django: http://en.wikipedia.org/wiki/Post/Redirect/Get
