Pottermore? A lot of people I was chatting to on twitter at the time got in! If you missed out or were safely tucked away in your beds dreaming of a romantic night by the lake with a young Sirius Black (or with Snape at Madam Puddifoots, whatever takes your fancy) then not to worry, you still have 6 more opportunities throughout the week to prove your magical worth and experience the site ahead of the October launch. Keep checking the Pottermore site daily!
For those who did register and validate your account through the email link, Pottermore have confirmed you definitely are part of the beta access! Third question here explains so. And if you login to your account, you'll see a nice little "Congratulations" message :)
So exciting! Cannot wait until this week is over and they start rolling out the beta phases. [Please let me be in the first batch to test it!] In the mean time, how about we all share our usernames? There's something slightly more exciting about sharing pre-made usernames than ones you'd make yourself. Don't ask me why.
Mine is: HallowHeart14. What did you pick? Later registrants, come back throughout the week and let me know if you got in! Can't wait to start Pottering with you all. :)
