get by with a little help

I'm doing a project for a university class regarding canon-based speculation about the Harry Potter books, whether the source is Web authors or LJers or fiction writers. It's a very anything goes free-for-all of the best and weirdest fandom's come up with. I'm looking for any special/eclectic resources and also have a few canon-based questions, as it's admittedly been a few months since I re-read the books.

- Any sites devoted to theories - conspiracy, speculation, or otherwise - relating to canon as set forth within the books. Everyone knows about Knight2King, but I'm sure there are heaps more out there. It doesn't matter how outlandish the proposition, I'd just love some off-the-beaten-path sources.

- Any sites that take an in-depth look at the books for whatever purpose, whether character development, hints for possible future events, to check facts (i.e. the population of Hogwarts, the ages of the Weasley siblings) etc.

- Any sites with archived interviews with J.K. Rowling, as I'm willing to consider what she says about the books and events as good as the words within them.

I'm fairly new to HP fandom and don't have very many people of that persuasion on my f'list, so any crossposting and/or links back here would be much appreciated, as, of course, is any advice and suggestions of anything mentioned here or that you think I may have missed. Sources used will be appropriately credited, as well as any contributors, should they wish to be. Thanks in advance!
