Some users are still having problems with the pop-up login. I think they are actually getting 403s because of the CSRF protection. So I have modified the base template to always have a javascript variable called csrf_token available when they aren't logged in. The ajax_login.js script was then modified to send this value with the ajax post. Fingers crossed.

<div class="smiley_farm">
{% for s in smilies %}
<img src="{{ s.image.url }}" alt="{{ s.code }}" title="{{ s.title }} {{ s.code }}" />
{% endfor %}
</div>
