I think that we don't need this. We decided it's clearer to keep these separate

This actually does now extend the django User model. The reason we hadn't before was that it didn't appear that it was officially supported in django.

More detailed explanation: I exchanged some emails with Ivan a month ago where he said django had added the ability to extend the user model. I had replied stating that the documentation still said to use "profiles" as the way to add data to the user model and that it nowhere encouraged extending the user model (which it still appears to do when referring to extending the user model). However, I later found other documentation about extending models in general (e.g. http://docs.djangoproject.com/en/dev/topics/db/models/#id5). It seems that some documentation just hasn't caught up and that extending models is fine, including the user model. It just has the caveat that with the way we do it, underneath it's actually separate tables. This is fine for us. We're concerned about simplicity and bug-free-ness, not efficiency at at the database query level.
