I've opened ticket #20629 [1] to track this problem -- hopefully we can get this documentation cleaned up so we don't scare others in the future. [1] https://code.djangoproject.com/ticket/20629 By way of explanation: Points 1 and 2 are asking you to consider an architectural question -- do you need a custom user model at all? If you actually *are* using a username-based login system, and you just want to track some extra information about the user, the right approach may *not* be to create a custom user model. Points 3 and 4 are pointing out known limitations. Proxy models are a problem because they use subclassing, and they will be subclassing the wrong class; signals are a problem because at the point the signal is registered, there's no guarantee that the User model has been correctly defined. There's not much we can do about (3); (4) is something that should get cleaned up when we eventually land app refactor.
