How to sign up for the Starcraft 2 Beta

In case anyone is wondering how they should sign up for the Starcraft 2 beta I'll post a short guide here.

Please note you will need to sign up a blizzard game at their website before you can get a chance to participate in the beta (You have to own a CD-key to do this)!
The following games are supported for this:
StarCraft, StarCraft Battle Chest, StarCraft Anthology, Warcraft III, Warcraft III: The Frozen Throne, Warcraft Battle Chest, Diablo II, Diablo II: Lord of Destruction, Diablo II Battle Chest

Step 1:
First of all you will need to create an account at Blizzards new battle.net homepage if you don't already have one. If you do have an account skip to step 2.
For Europeans that would be https://eu.battle.net/login/ and for Americans the link is https://us.battle.net/login/.

Step 2:
If you already have a game registered under your battle.net account please skip to step 4.
Find the option called "Add a game" which should be located just under "Manage My Games".

Step 3:
At this point you will need to dig out one of your old blizzard games (check the list earlier in this post) and enter the corresponding CD-key in the box. Hit the Add Game button and if you entered a correct key you'll notice the CD-key/game becomes connected to your blizzard account.

Step 4:
Return to the battle.net main page and find the option called "Beta Profile Settings" located under "Manage My Games". Here you'll have to download a small file that tests your system and uploads the info back to your battle.net account.

Step 5:
Make sure you choose the beta categories you are interested in. This is not limited to Starcraft 2 but you'll have the option to enter beta tests of the Diablo universe and the Warcraft universe also.

Step 6:
Keep praying and you might just get lucky and make it into the Starcraft 2 beta! ;-)
