any special action required to "turn cata on"

[Lunabaduna]

HELLO!

i bought myself a digital copy of cata a couple of days ago.
Do i have to do anything else to activate it, so it's good to go tomorrow at 23:59 ?
like, typing the CD-key in somewhere on battle.net?

thanks

Nope once bought your account management should state that you've upgraded to Cata, there is a blue post somewhere stating all you should have to do is log off and back on again to get your XP bar on cata release.
