[Facebooker-talk] facebook_session not working for me

I'll take a look at that - but isn't the point of the exercise in the
book to get the user to install the app?

I'm following along in your book and having User A send User B an
invitation.  User B clicks to accept the invitation and install the
app... but it can't set profile_fbml yet because User B doesn't have
the app installed...

What am I missing there?

Thanks for your help!!!

Here is the entry from the server log, including params:
