I have an old Gmail account that is bound to my Android cellphone and everything else.
The old mail address is too long, so I made a new account with a shorter address.
Now I tell people my new, short email address.
I can check email forwarded from the new account using my old account(delegation).
But if someone were to invite me into a chat using my new account, how will I get notified and chat with that person, using my old account, as the new account without revealing the old account ?
How do I chat on behalf of another gmail account ?
