This plugin allows the following you to configure the backend new user screen to incorporate the following features
<ul>
<li>Optional use of email addresses only instead of username and email.</li>
<li>Optionally hide the new user url field</li>
<li>Optionally allow you to specify whether an email should be sent to each new user or not</li>
</ul>
These changes make adding new users to WordPress a lot faster.
One word of caution is that IF YOU USE EMAL ADDRESSES ONLly the plugin replaces the username with the email address of the user when a user is saved in the database. meaning your users will no longer have a separate username.
