UPDATE: non-U.S need manual proxy to join. Use 208.96.213.149 and port 80 (very slow)
then use this link: http://www.stardoll.com/en/clubs/home.php?id=1469788

Get Free Items when you join Club Wizards on Deck. If you are from another region, other than U.S try using myproxy.ca to join. Let me know if this works.
