Every day for the next six days, a clue will be posted on the site. No one knows what time it will be posted and it won't stay up for long because they're only allowing a certain amount of people to register each day (the first clue was only available for about two hours), so you need to constantly check the site throughout the day to see if it's up yet and answer as quickly as you can.
Once the clue is posted, you work out the answer and then type in this url:
link and add the answer to the clue after the "/" in the url (for instance, if the answer to the clue was "luna" you would go to
link).
If you get the answer right, it will take you to a Sony site where you will be asked to find the "magic quill". Somewhere on that page you will see a quill feather that is glowing. All you have to do is click the quill. After that you'll be taken to the registration page. Just follow the instructions from there! If you get stuck again, feel free to message me and I'll help you out! :)
P.S. The answer to each clue can be found in the books. The first day, (today) the clue was about The Philospher's Stone, and the second one (tomorrow) will be about The Chamber of Secrets, the third day's clue will be about Prisoner of Azkaban (and so on).
