Ticket #15942 - Username vs. Email for Identifying Users

Reported Problem: “When I create a new blog in a network, I am asked to enter the Admin Email. This is rather useless to me because all our accounts come from an LDAP directory. So I have to remember the site admin’s email address, which is not always consistent across my organization. It would be nicer if I had an autocomplete-style field where I could enter the user’s ID.”

The issues of selecting existing users vs. adding new users and doing so by email address vs. username touches more admin interactions than just this one. We’ll need to address it as a whole rather than just focusing on this one person’s complaint, but using this ticket as a starting point for discussion.
