I inscribed myself just after dinner with OpenID: http://openid-provider.appspot.com/ thinking it was the right way to authenticate a OpenID account, unfortunately now I created an account there and I can't login any more :(
Unable to log in with your OpenID provider:
Positive assertion sent with OpenID version 1.1 but Identifier discovery suggested would be 2.0.
How can I get back to my old account? :(
