The Pottermore Insider blog has been updated to answer some more frequently asked questions. Fans will be most excited to learn that they have revealed a time frame for the third clue release. It is not an exact time, but that is better than nothing so you don’t have to stay up all night. The clue will be released between 9am BST (4am EST) and 1pm BST (8am EST).

Another question that may be of interest to fans is the following about selling/buying Pottermore accounts:

I have seen Pottermore early access accounts being sold online on places like eBay. Is it okay to buy or sell Pottermore accounts?
No. Please do not buy, sell, or transfer Pottermore early access accounts. Obtaining Beta registration for Pottermore with the intent of selling on those registration details for monetary gain not only deprives genuine fans the chance to gain early access, it is also expressly prohibited in The Magical Quill promotion Terms & Conditions.

We have the right to terminate any Pottermore accounts that are sold online.

Access to Pottermore is, and always will be, completely free so please don’t be tempted by people selling Pottermore accounts online. You will only be wasting your money – and there are still more clues and chances to come!

Finally, for non-English fans this question may be of help for some remaining clues:

Did some of the translations of Harry Potter and the Philosopher’s Stone contain a different answer to the first clue?
Yes, some of the translations only referred to four of the five owl types when describing the Eeylops sign. We are double-checking the consistency of the translations for the remaining clues but, when in doubt, please always refer to the original English versions of J.K. Rowling’s books.
