Blizzard is reportedly sending out beta invites to Diablo III. So, have you checked your inbox to see if you’ve received yours yet? There are supposed to be 100,000 invites that were sent out by Blizzard in North America alone.
You can also try logging in to your Battle.net account just to be sure. If you haven’t received any invites, don’t fret. Blizzard has said that this is but just a start and they will send more beta invites in the future.
In saying that, don’t forget that despicable people use opportunities like this to dole out phishing attempts. So, be cautious of suspicious looking invites.
