Pottermore may be really great once it's fully up and running but I think right now they may have overestimated themselves by thinking that they would open the beta site to 1,000,000 million users by the end of September. Somehow I don't even think 250,000 have been given access yet. Yes some of us have noticed that they did not address the issue on how the emails were being sent and in what order. That is because they aren't doing what they initially said they would do i.e first-come-first serve. It looks to be on a random basis. So yes, while many of us stayed up long nights to wait up for the challenge, for most of us, doing that may have been a waste of time.
Right now it sounds like they are on pause mode again after the last batch was sent yesterday, so the waiting game begins again for the rest of us, and while we wait, we might as well get ready for the start of a new school term at Hogwarts here in SS.
For those who got early activation in, congratulations. After having said this, not wanting to sound like sour grapes, but would it be possible for you to post your experiences on Pottermore on a separate thread? You know...Spoilers!! (SS could you note this suggestion please?)
Chin up everyone. Someone once said patience is a virtue. If I didn't know better I would I have thought that it was the guys over at Pottermore

. I know that our patience is wearing thin but we'll get in eventually even if it's after the end of September.
