The Comic's section dedicated to all things Buffy was left unused for a time while Joss worked on other projects but it's back now...the first installment gives interesting background on how Buffy Season #8 came to be. I learned something here...never realized how important right vs lefthand pages were! Anyway, this is a nice site for fans as it links to books, comics etc.
