Ron,

DG is correct. A lot of people who have WoW accounts are getting password phishing emails for Diablo. Blizzard is conducting beta invites only through your online account at us dot battle dot net. The link in your email is a bad link. You may wish to scan your machine for malware.

Anything you get in email that has a link to a site for Blizz related stuff is most likely fraudulent.

Best,

Bogey
