Can this be read only for the user

The idea of this plugin is that it’s admin’s only who can view the notes. You can get around this though by installing a plugin like My Custom Functions and pasting the following into it:

function custom_user_notes_show_field($wp_user) {
  //Don't show the non-editable version to admins
  if(current_user_can('list_users'))
    return;

  $notes = get_user_meta($wp_user->ID, 'user-notes-note', true);

  ?>
    <h3><?php _e('User Notes', 'user-notes'); ?></h3>

    <table class="form-table">
      <tbody>
        <tr>
          <td colspan="2">
            <div><?php echo wpautop($notes); ?></div>
          </td>
        </tr>
      </tbody>
    </table>
  <?php
}
add_action('show_user_profile', 'custom_user_notes_show_field');
