{#
This template is referenced by the confirmation code and does not have the
requisite context to make a useful signup form. Therefore, we immediately
post to another view which executes in our code to produce the desired form.

<form id="register" action="/accounts/register/" method="post">
    {{ csrf_input }}
    <input type="hidden" value="{{ key }}" name="key"/>

    <input type="hidden" value="{% if full_name %}{{ full_name }}{% endif %}" name="full_name"/>
