Recently I registered an app in http://stackapps.com/ to provide a way to authenticate users with their Stack Overflow account.
Then I noticed that https://stackexchange.com/oauth only works for users with a StackExchange account.
I didn't find a way to set the authentication for only users with a Stack Overflow account in the documentation site .
I've faced with this problem because I want to collaborate with the Django Social Auth project for allowing the authentication with Stack Overflow.
