From pottermore.com ” In the new website, the storyline will be brought to life with sumptuous newly-commissioned illustrations and interactive ‘Moments’ through which you can navigate, starting with the first book, Harry Potter and the Philosopher’s (Sorcerer’s) Stone. On entering, you choose a magic username and begin your experience. As you move through the chapters, you can read and share exclusive writing from J.K. Rowling, and, just as Harry joins Hogwarts, so can you. You visit Diagon Alley, get sorted into a house, cast spells and mix potions to help your house compete for the House Cup.
At a press conference at the Victoria & Albert Museum in London, Rowling revealed some key features of the website. In an announcement which will thrill fans, she described how she has brought to life both the Sorting Hat and Ollivanders experiences from her books for the first time on Pottermore, by revealing the questions asked by the Sorting Hat – which places newcomers into their Hogwarts houses according to their characteristics – and the magic behind the Wand Chooser – which finds the right wand for each user from over 33,000 possible combinations. She also revealed glimpses of the new information she has provided on some of the best-loved characters. ”
