Compatibility with U Create

It would be nice if this module was compatible with U Create.

With sharedemail enabled, if a user only had "(ucreate) create users" permission, he won't be able to create new accounts using an existing email if he did not have "administer users" permission from users module.

It gives you this warning: User with this e-mail address already exists.

Unfortunately, I can't grant "administer users" to those users, but I'd need them to be able to create users with shared emails.
