 just another user datum, like URL.  The current system, which de facto
 requires email addresses, makes it tricky to implement authorization or
 authentication protocols such as OAuth or OpenID that don't necessarily
 get you a user's email address.

 email addresses.

 I agree with Filosofo. This seems to be more of an issue with
 email_exists() not being cope with being passed an empty string which is
 the default behavior of some of the functions which rely upon it. If
 email_exists() is passed an empty string, perhaps it automatically return
 false without searching the users table.
