Google+ decided to let me IM with people in my circles. But I only ever notice IM messages if I log in to an account via Pidgin (a desktop XMPP/AIM/etc. client). Google offers XMPP login to its chat system.
However, what is my XMPP username (and domain, e.g. gmail.com)? I don't have a Gmail account on this Google Account.
Is it possible to log in via XMPP to chat with my Google+ circles without GMail-izing this Google Account†?
A Google Talk help page suggests it's possible to have a username without Gmail, but not how to create such a Google Talk username.
I tried https://talk.google.com/ . It solicits me to install their proprietary software/extensions locally, rather than just letting me sign up for a username; are those extensions:
- a way to do so; or
- the only way to add a Talk-but-not-Gmail username to my existing Google Account?
I'd prefer if there's a Web+XMPP—only way of doing this, if possible.
†I don't want a Gmail account with my Google Account because it would become my primary email for this Google Account, which has various negative effects for me.
