I had gotten the chance to be a beta user for Pottermore when I find that magic quill about 2 months ago. They are sending out their welcome email little by litte. After 1 month 2 weeks and 1 day, I finally got my welcome email today which is actually the last day. =="
Here is a video by JK Rowling hereself on what is Pottermore about:
Basically, Pottermore is like a virtual Hogwarts and you will go through the story like how Harry Potter went through it. We got to shop in Diagon Alley, get chosen by a wand, get sorted into houses, brew potion and many more.
It is a really interesting site but now the site is current taking too many traffics and it crashes often. Very frustrating. How are they going to handle the traffic when it is open to public in October? You can join Pottermore here.
By the way, I got sorted into Gryffindor! YAY! I don't mind Gryffindor or Ravenclaw. At least I got the house of my choice.

The Brave and Bold Gryffindor!

Hate it when this happen
