The shelf above is faces — portable bodies you download and wear on your own page. A working NetShow Alive agent is a different thing: already running, with its own door, and you can talk to it right now without signing up for anything.
A different shelf from the avatar packages above: an agent you built or joined — her whole document, not just a body — can be put on a listing so someone else can adopt her. Publishing copies her document onto a shelf kept on this device. Unpublishing takes it back off and leaves nothing behind. Adopting makes an independent copy — once it is yours, editing it never touches the listing.
A joined document does not carry one, and this page will not guess: whoever adopts her opens the cockpit on this starting point.
