def save(self, *args, **kwargs):
    application = Application.objects.create(form=self.form)

This seems to be related to this line, in ApplicationForm we initially create an application for that form_id with no e-mail. Afterwards, we loop through question types and assign an e-mail to the application.

According to code, it looks like there could be forms that don't require e-mails, but I wonder if we accept applications without an e-mail? Maybe instead of calling objects.create we can just instantiate an Application record and save it when we post process the forms questions and answers?
