Nabble <-> GoogleGroups

Hi! I must have missed something.

I'm trying to use Nabble to archive my google group. I filled the form on the home page and was expecting  to receive an email address that I would invite to the group.

Alternatively I was expecting a subscription request to appear on the google groups.

None of the two things happened. Should I have done something differently?

I verified messages are not sent from the Google group to the Nabble (and I fail to understand how they could without an email address) .

Any suggestion?

Thanks
