We have a new page on Accio Quote! where we have taken everything we can find that J.K. Rowling has said about her last book and weighted each statement for importance. Then the staff had a crack at guessing what it all might mean. The title is "Hint, Hint: JKR on Book 7, What We know abut Harry Potter and the Deathly Hallows."
Leaky fans will recognize this as a chapter in the Leaky/Floo Network book entitled "Harry Potter Seven," a fundraiser for Book Aid International. If you wish, you may now donate from our site -- it all goes to the same great cause in the name of Potter fans worldwide. Donations are entirely voluntary.
This makes two ways you can browse Rowling's statements about Book 7: by importance or by character/topic.
If you want to discuss any of this there is a special thread on the Leaky Lounge forum.
