I'm glad you got your answer! It really is a must these days with all the hacking that goes on. Lately I've been getting phishing emails from people pretending to be Blizz. The most common lately is the one where they say my Battlenet account is frozen because of suspicious activity, and please click the link ..... Needless to say I don't click the link and keep forwarding the emails to Blizz.
One thing that makes me angry is how our email addresses get out there. The security, outside of the Authenticator, sure isn't tight. I don't do the friend thing so my address shouldn't be anywhere but in Blizz's database, but someone has it somehow.
