Yeah I'm a Harry Potter fan and I'm not afraid to admit it. Therefore I would like to mention that Pottermore.com is a pretty cool website, if you’re into the Harry Potter series. While it’s still in its early stages, my personal favorites are mixing potions, Ollivanders explanations of wood and cores used to make wands, and the welcome message you receive when being sorted into a house. Which leads me to my final statement:
Its pretty fun, but you can't make your own profile name or really chat or message with other players. They're trying to keep it child safe. But other than that yeah you should check it out.
