Neither my sphere nor wand work. I'm a squib I guess.  And I just don't have the gene for using the sphere.

There is a wiki specifically designed to capture the stuff from Pottermore which I have used multiple times. I've mostly only read the new information from JKR information. I stumbled across it one time when I was looking for some bit of canon answer for the story. For example, I was wondering if one needed a wand to call the Knight Bus, but the content here says "stickes out their wand arm" not "hold up your wand".  Yoo-whoo- something that can be done without a wand and without wandless magic.

 I have not read all of these.

I don't know if they'd copy these whole new stories out there, however.  I can hope. :)
