thanks, i had a hard time figuring out the correct solution due to all the comments in the /snippets/74/ thread.

Nice solution, thank you.

I did find a tiny edge-case problem with users who registered on my site, unregistered themselves, then re-registered again because this caused the User.objects.get() line to return > 1 result. To fix it, simply change, user = User.objects.get(email=username) to user = User.objects.get(email=username, is_active=True) on lines 16 and 22.
