Ebay is having a tough time shutting these down, but offers to sell Pottermore accounts are popping up everywhere. Pottermore - for those who are not infected by Potter mania is a website by Sony along with J.K. Rowling and will have additional details to the original books as well as e-book and audio book versions. Registrations were open to the first million users from 31st July 2011 and wont open to the general public until October 1 , 2011. The site offers a virtual Harry Potter world with never before seen / heard details of the Potter’s world.
Actually, the website launched on July 31st, 2011, with the "The Magical Quill" quest which would allow users who completed the quest the "early" registration for the site. The quest would run for 7 days, from 31st July to 6th August. Each day, a clue from the corresponding book (day 1 Philosopher's Stone etc). The clue must be answered correctly to enable the person the right to register before October.
Roughly 150 thousand people will be able to register each day. After the quest is over, one million people will be selected to view the site before October. For those who have the cash and do not need to raid Gringotts like the rest of us, head on to Ebay for auctions like this one (its still live as we write) and try your luck. The rest of us can simply keep trying everyday and have their fingers crossed.
