Hi, did You found any easy and good Wordpress plugin which email user when his wordpress user account role is changed? (author, contributor, subscriber..)

so far i used this manual code editting hack:

function user_role_update( $user_id, $new_role ) {
    if ($new_role == 'author') {
        $site_url = get_bloginfo('wpurl');
        $user_info = get_userdata( $user_id );
        $to = $user_info->user_email;
        $subject = 'Role changed: '.$site_url.'';
        $message = 'Hello  ' .$user_info->display_name . ',

Your user account role was changed at  '.$site_url.', new role is: "' .$new_role. '".
Thank You';
        wp_mail($to, $subject, $message);
add_action( 'set_user_role', 'user_role_update', 10, 2);
This should be pasted on the second line (after first line which is: <?php) into functions.php file (Wordpress/Appearance/Editor)

if($new_role == 'author')
this can be also contributor, cubscriber etc...
