diff --git a/Delete facebook group members (all the one visible on a given page) b/Delete facebook group members (all the one visible on a given page)
 /**
 *
 * This script will remove all group members displayed on group page except admins.
 *
 * @author: Nir Geier
 * @modified: Ken Carino
 *
 * Updated May 29, 2019 - Tested on Chrome Version 74.0.3729.169
 *
 * Requirements:
 *    1. Facebook must use english as language
 *
 * Usage:
 *    Load as many users in group members page, then open console and paste this script in the
 *    console. All members loaded in the page will be deleted by this code.
 *
 *    Once the script finished executing, the page will automatically reload.
 *
 *    If looking the console doesn't give any feedback of what's happening, reload the
 *    page and repeat again. Take into account that it will delete one user per second,
 *    so it may take a while.
