JK Rowling launches Pottermore website

Harry Potter fans have the promise of more wizarding adventures after JK Rowling launched a mysterious website called 'Pottermore'.

The project was unveiled when Rowling set fans a series of clues, asking them to enter 10 sets of coordinates into a site called secretstreetview.com. A letter could be found at each location, spelling out the Pottermore name.

The website bears Rowling's signature and the message: "Coming soon..."

Her lawyer, Neil Blair, refused to reveal what the website would contain, saying only: "This is not a new Harry Potter book."

It is believed that the interactive site will be a meeting place for fans offering games, a Harry Potter encyclopaedia, readings by Stephen Fry and competitions. Fans will also be able to buy the books.

Potter fansite The Leaky Cauldron has been granted a sneak preview of the content and described it as "one of the most amazing, engaging and breathtaking additions to this fandom imaginable".
