Copied From Pottermore Insider:
Since we launched Pottermore, our one million Beta users have given us lots of amazing feedback, and we’ve been collecting their thoughts and comments so that we can make Pottermore the best experience it can be before it opens to everyone.
After looking closely at all the information that we've gathered, we have decided to further extend the Beta period so we can improve Pottermore before giving more people access. This means the site will not be opening to new users in the immediate future, but please know that we will open registration as soon as we can.
As part of our work to make Pottermore even better, we'll be taking the site down for a few days on Wednesday 2 November. We're going to use this time to make a few technical changes behind-the-scenes.
We've set up a separate page on the Insider so we can give you the latest Beta information and answer some of the more common Beta questions. We'll be updating it as the Beta continues and posting on our Twitter account, too.
So Pottermore will not be opening to new users just yet. For all of you who are waiting to enter Pottermore, we want to thank you for being so patient - we’re working very hard to make some exciting improvements, and we're really looking forward to welcoming you to the site when it’s ready.
