Pottermore!
I figured since several of us have Pottermore accounts here would be a good place to share user names, what house and your wand information if you wished!
Also just to pimp my friends Facebook page there's a great community on Facebook for all Pottermore folks called the Pottermore House Common Room. I've made a lot of friends there and they're uber helpful if you have any questions.
So -
User Name -
House -
Wand -
Whatever else you wish to share!
