Your last chance for early registration is 12:30 am- 4:30 am British Standard Time. आप just have to figure out what time that would be for where आप live. The final clue for it will go up then.
आप have to figure out the awnser to the सवाल 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 आप to the website where the Magical Quill is hidden. All आप have to do is find the quill and click on it, and it will let आप register.
When the clue comes up it will be the last one so आप have to get that one otherwise आप will have to wait till the site opens to all in October.
Hope this helps, and Good Luck. I luckily got in on दिन 5 द्वारा checking randomly and the clue was up.
