GS was heavy on magical theory. Harry had to confront false assumptions and learn new things about the nuts and bolts of his trade, which was totally awesome. There are a lot of topics on the spoiler boards that deal exclusively with magical theory in the DV.
Might it be a good idea to, perhaps, devote an area just to that? We've been given loads of new information, and we have a whole bunch of new questions about how magic works in the story universe. I suspect that, over the next few books, we're going to be seeing a lot more of that. That opens the door to oodles and oodles of new speculation. Putting it all together would seem to be a good idea.
Thoughts?
