Steps: 1. New user that has twitter account comes to my sign 2. Use "Sign in with twitter" button to authenticate. 3. Once it is authenticate through twitter, I want to have his twitter's username as the username on my site. As long as it passes back the username, I can assign that username to the signup form on my site. I've been googling google for the know-how, but with little luck. Please advise.
