can i register to Pottermore now and how can i do this ?

If Du did Abschicken your E-Mail Du have to wait for the clue which comes out at different times

Off the Website: link

Those of Du who would like the chance to gain early access to Pottermore must find The Magical Quill and then Abschicken their registration details. Each day, from 31 July to 6 August, a clue will be revealed here. Solve the clue and Du 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. Du just have to figure out what time that would be for where Du live. The final clue for it will go up then.
Du have to figure out the awnser to the Frage 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 Du to the website where the Magical Quill is hidden. All Du have to do is find the quill and click on it, and it will let Du register.
When the clue comes up it will be the last one so Du have to get that one otherwise Du will have to wait till the site opens to all in October.
Hope this helps, and Good Luck. I luckily got in on Tag 5 Von checking randomly and the clue was up.

if Du want to register in Pottermore go at the time when Frage is there if it is there read the grey box on left side of your Frage and do as it is written
