Those of あなた who would like the chance to gain early access to ポッターモア must find The Magical Quill and then 提出する their registration details. Each day, from 31 July to 6 August, a clue will be revealed here. Solve the clue and あなた will be taken to The Magical Quill. Be quick, The Magical Quill won’t be there for long and registration will only be open while spaces are still available each day.

Your last chance for early registration is 12:30 am- 4:30 am British Standard Time. あなた just have to figure out what time that would be for where あなた live. The final clue for it will go up then.
あなた have to figure out the awnser to the 質問 it asks. (It will have something to do with the DH book). Then put it at the end of this URL. link
Doing that will take あなた to the website where the Magical Quill is hidden. All あなた have to do is find the quill and click on it, and it will let あなた register.
When the clue comes up it will be the last one so あなた have to get that one otherwise あなた will have to wait till the site opens to all in October.
Hope this helps, and Good Luck. I luckily got in on 日 5 によって checking randomly and the clue was up.

if あなた want to register in ポッターモア go at the time when 質問 is there if it is there read the grey box on left side of your 質問 and do as it is written
