connected to nabaztag.com - and now?

I just found my old nabaz:tag v2 in the attic and got it back online.
It connected to http://openjabnab.fr but there is currently no login possible and all seems stopped.

I set him to connect to www.nabaztag.com and he's currently showing a smooth animation on 3 LEDs, dimming in and out, so all should be up and running.

Where do I find my rabbit on which website?
How do I configure my rabbit?
How do I add it to http://nabz.wizz.cc/ as I have no Token?
