Blizzard recently added a
Beta Opt-In Program on the new
Welcome to Battle.net site.
What do you do?
Go to
Welcome to Battle.net and login (or make an account if you haven't done so already). After that, click the "Beta Profile Preferences" link on the main page after logging in.
From there, you can download the Beta Opt-In program which will scan your computer's system specs and send them to Blizzard. After the upload is successful, you get to select which Betas you are interested in trying: those related to Diablo, Starcraft, Warcraft, or any or all of the above.
I'm presuming this is so Blizzard can select people with a wide range of system specs to see how well their newer games will run on them.
Anyways, if you're interested, go Opt-In already!
