Go here:
Just updated yesterday, every Q drop with a good bit of explanations (especially in the middle), 852 pages long.
When I first got here though, in early April, I tracked down what looks to be one of the first copies of the book of Q. It only goes until the end of April but I liked it much better for the beginning than the PDF above because the explanations more in depth. The newer PDF is great but doesn't have, I don't think any at all, explanations in the first month or so.
I just uploaded it in case anyone wants it; good for getting newfags started: http://anonfile.com/cfQbn9e3b7/Book_of_Q_-_V1.pdf
