Well, something's not quite right, because I applied on Thursday (the 2nd) and I don't use spam filters at all... I own and administer the domain of the email address I submitted, and I can say with 100% certainty that I haven't recieved anything from any email address ending with @blizzard.com since then.
Cairenn, you are a GOD for following up on (and putting up with) all of the complaining!
