Hey I bought a 4 pack of the game. Received the email and all is generally well with that. But I have used two of the four links. One for my email, one for my daughter. Do I have to 'claim' the other two links before the beta starts, or can I give them to friends after it starts and they can claim the keys? (dont want to hand them out till I know people will play) Can I claim the links myself and just have them all go to one email account? Then when I get the emails after beta I can just give the steam keys out to friends?
