From today morning I can't login to Stack Overflow and other Stack Exchange sites. It throws an error.
Also, the login page doesn't show any OpenID providers.
I am using IE 8. I have tested this also with IE 7, the same problem exist everywhere.
PS: I can login to meta because I have enabled remember my login while login to meta sometime before. So it automatically allows me in.
I have a question, Since all the Stack Overflow sites share common logins, why don't you automatically allow me to login to other sites if I already entered in one site (something like Gmail & orkut).
