[Design] Who modified this item?

[Jeffrey Harris]

Hi,

If I have three email addresses set up, and I change a shared item,
which email address should we use use when sharing "lastModifiedBy"?

In the UI we display "last edited by me", which is all well and good,
but until we have a more thorough identity concept in Chandler, we're
just going to share an email address.  Should there be a way to change
which email address is used?

Sincerely,
Jeffrey
