Option to manage connected OpenID's and multiple OpenID support
There should be an option in the user control panel settings to allow the user to manage the OpenID he connected with his UserEcho account, e.g. remove or change OpenID.
You should also support the addition of mutiple OpenID's to an account. This allows the user to be protected from being locked out of his account if his default OpenID provider discontinues their service. There are many websites out there that allow connecting multiple OpenID's to a user account.
We support linking at this moment but seems, that it not clear for the users. UE auto-links accounts with the same email if it verified. We consider about adding information to user profile with linked accounts info.
