Tomorrow, Thursday the 11th October, from 5:00pm BST (12:00pm ET/ 9:00 am PT), J.K. Rowling will be answering questions about Harry Potter (including Pottermore) from children around the world in a live webcast.
You can view the webcast on the Scholastic website (for the US version of the site) or on the Bloomsbury website (for the UK version of the site) and watch it live, as it happens.
In the webcast, J.K. Rowling will also be answering a Pottermore-related question that you, our Pottermore fans, voted for at the start of September - 'Which Pottermore house are you in?'.
