I made the mistake of registering on Stack Overflow a while back with an Appspot OpenID, and not the real Google one. I have got some good rep, and don't want to start again or lose answers to my questions.
When I try to log into SO using Chrome I get this error:
Positive assertion sent with OpenID version 1.1 but Identifier discovery suggested it would be 2.0.
for my OpenID.
And weirdly when I click the Google icon on the login page, I get logged in with an
unknown(google) account automatically.
How do I go about creating a valid Google OpenID and then adding it to my SO account? I seem to be able to log in OK with Safari.
