I log in to Stack Exchange using a Stack Exchange account (just Stack Exchange email and password – no Google, Facebook, etc.). So far, so good.
But when I try to login or sign up to another Stack Exchange community using this authentication, there is no option for adding it to my profile. I have only these 3 options for sign up:
- Completing a form for a new id
When I visit the sites that I'm already associated (like this Meta or English Leaners), everything works well, I'm correctly authenticated.
How can I become a member of other Stack Exchange sites? Am I facing a bug?
