            The <i>Author Autofill</i> plugin automatically copies user information
            into specified metadata fields in new resources records when they are
            created.
            <br/><br/>
            Up to three values may be automatically copied.  For each value you want
            copied, set <i>User Info</i> to the appropriate value from the user
            signup information and the corresponding <i>Metadata Field</i> to the
            metadata field you want it copied into.
            <br/><br/>
            If you want to copy a non-standard
            user signup value, select <i>Other</i> for the <i>User Info</i> setting
            and enter the user info value name (as passed to <code>User::Set()</code>
            in PHP) into <i>Other Value Name</i>.
