Hello everyone. I was wondering two things. First thing is can two different people use one starcraft 2 account to play the game or do you need two separate keys? Second thing is, I'm getting a starcraft 2 key tomorrow and I'm going to be getting a whole new computer Saturday. So, if I download starcraft 2 on this computer tomorrow will I be able to use the same key to download it on my new computer less than a week later?
