They must have applied for the certification of Diablo 3 gold.
Some players have got the certification of this beta. They must have applied for the certification of Diablo 3 gold on American server. If you haven't applied for one, register soon. Since American server has distributed many accounts, next time there won't be such good opportunities. So players should catch the opportunity. If you wanna register in eu server.Pay attention: site address starts with eu instead of us. Default country is British, France, Germany, not American. Players choose British. The district for players paying should be eu, which means Europe. In sake of safety, don't register accounts in other districts with the account that you have registered in American server.
