where exactly do you find your key for sc2 beta? I logged in and everything, and it works but you never enter a key or anything and I need to find mine to sign up for the sc2 beta forums...
I don't think they give out keys anymore. They just put it onto ur account. =/
Due to people selling keys, once the game is on your account, all you need to is login. If you have a sc2 beta attached to your account, bnet will recognize it, and the account registered to it (sample.account) and you as an authorized user. It was only previously that you required to submit your key.
