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.

{% load url from future %}
{% load markup %}
{% load smiley_tags %}
{% load bio_tags %}
{% avatar user 0 "left" %}{% profile_link user.username %}:<br />{{ msg|safe }}
