Rely too much on author's website. If you dont believe me just rename "ma-group5.com" to "example.com" in all the script. This script become useless. Do you want your precious business depends on author's server uptime? What if his server get down? Everytime the script do a "function" it called the author'server. If the server is down the "function" failed. But the author keeps deny that this script doesnt rely on his server. He lied all the time.
