Space Management

I should be able to change the creatorship / ownership of a Thing: Requested by Eric, as part of managing his Space. He makes use of _creator for a bunch of stuff, but that raises a problem: how do you change that? How do you reassign the "ownership" of a Thing? It's a reasonable desire.

I should be able to moderate the use of Display Names in my Space: This needs thought and design, but it's a reasonable request.

I should be able to see the recent activity for a particular Person: Requested by Eric, as a way to help distinguish multiple Persons with the same Display Name.
