Mahmoud: The problem is that won't recognize if the user changes their email address; it'll create a new entity and the user will lose everything.
yejun: I thought about that, but there's no way to automatically know that a new email address was changed from some old one. User interaction is required. This requires an additional security system to be built to verify that the user did indeed have the old email address originally. There's also a possibility that the user will start creating new content before realizing there's a problem, creating the hassle of trying to merge the accounts. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
