Thank you for your answer.
I'm a newbie in google api and opensocial stuff, so sorry if my
questions are to simple.
I played a little with opensocial (in this case 0.7). What I can
receive inside a container is e.g. the
- Name of the viewer (viewer.getDisplayName()) - but this is working
in orcut not in igoogle.
- the ID (viewer.getID()) - this seems to work everywhere.
So I could use e.g. the ID to create my user in my database and
recognize him.
But I would prefer to know the viewers email address, this should also
be uniqe.
Here are two questions:
- How can I get the viewers email address?
- If one is not logged in, he is never able to add a gadget somewhere?
In other words - can I assume, the a user, who uses a gadget is logged
in to a google service? What happens with the viewers data, if he adds
a gadget to other websites, is the ID or the google email address also
available there?

Thank you
Torsten
