With the books and movies all finished, are you suffering from Harry Potter withdrawal? Maybe it's time to head over to Pottermore, an online hub developed by J.K. Rowling for fans of the boy wizard. The free site is now open for all to join. 

Users will be treated to additional writing from Rowling that augments the books, digital games extending the series' themes and plot-lines, e-book reading and a platform to talk muggles and magic with other Harry Potter fanatics. "The digital generation will be able to enjoy a safe, unique online reading experience built around the Harry Potter books," Rowling says in a video introducing Pottermore.

After signing up for the site, you'll get assigned to a Hogwarts house by the Sorting Hat and be specially chosen by a compatible wand before diving into the site's content. You'll be able to friend other Pottermore users, take on magical missions, compete with other Hogwarts houses and more deeply explore Harry's world.
