I have a bone to pick with you about CSRF.

This if feedback regarding your signup process and your issues process, pretty much every sensitive form you have...

Checking referrer fields is not CSRF mitigation, In fact I am surprised you haven't had more complaints about it.

Also your error page is big and ugly, and discloses details on how to ex-filtrate more information from your system, indicating the use of "DEBUG=True".

I had to switch from FF 8.0 because I couldn't submit any forms on my main browser...
