[Qx3] Buying Warband

[Servitor]

Hey,

I've finally kept onto my money long enough to now be able to buy Warband! Yay. But there's some things I would like to be reassured about.

1) Buying the game will sent me an email with the activation code? The whole billing address thing kinda freaked me out, as if I'm getting a delivery.

2) Are there any problems whatsoever with yahoo.co.uk emails? Happens to me quite a lot that .co.uk results in the sender giving me the finger.

3) Is opening/forwarding ports necessary for playing this game Multiplayer? Wasn't so at the beta but I've seen it being thrown around in tech support.

Thanks in advance,
Servitor
