There are some details that I only thought of after emailing.
We notify people via DM of account creation when they sign up via
OAuth or following @tipjoy. That includes a temporary password.
Despite being able to sign in with twitter, passwords are still used
to change passwords and request a cash out.
We'll need to figure out how to get those users to set a tipjoy
password without being able to DM or email them.
The best solution requiring no work from me is to just make them
follow @tipjoy before doing a notify.
