Another Pottermore question

This probably gonna be an ongoing thing with me asking questions, until I get the hang of the pottermore website.
But I'm wondering, how do you advance to the second book? I have finished the first book and JK Rowling said her congrats and whatnot, but I can't move on; I'm still stuck on the last chapter of book one.
Is there something I have to do first, like gain more house points or something?
