Comment:

 I'm reopening this because it introduces a regression.

 While the initial intent (not allowing multiple user registration) is
 reasonable, it introduces a problem as follows:
  1. Set up WP
  1. An admin user is created
  1. User's email is set to my email address
  1. I want my posts to show up as from me.
  1. So I create a new user (me) with my address.

 Before this fix, this worked. After this fix, it stopped working. So,
 today, when I did a fresh install, I had to enter a bogus email and then
 change it in the DB backend.

 Another option would be to be able to change the default admin account's
 username, but that can be problematic - better to just allow the creation
 of multiple accounts with the same address from the admin panel (perhaps
 with warning).
