it's a closed beta and keys are hard to get, but i got lucky on ebay and made a deal that i came out with 10bucks more and a valid beta key xD
so i was wondering if anybody else is participating, too?
ps: my personal estimation is that betal will start in june, so still enough time to grab a key ;)
How do I get a key?
look it up at starcraftwire.net
I found out how for anyone interested.
Look at blizzard.com and on the front page there is a blurb about getting a beta key.
All you need to do is create a battle.net account and change your op-out settings.
You will need a Blizzard game in your profile to qualify for a key.
that way you gotta be really lucky, like 1 out of 10000. but it's a good idea to activate the opt-in option cause it only takes a minute and doesn't take any money, risk-taking or creative effort.
