I really should read my e-mail more carefully. Yes, Heaven and Hell was nominated for Best WIP. And also for Best Spike Characterization, Best Crossover, and Best Future Fic. *blushes*
I don't consider it a crossover, though... I take TtH's view of crossovers. A cross of Buffy and Angel is not a crossover. Yes, they are two shows, but one's a spin off of the other one. There's no cool and interesting ways to mesh the universes, because they are the same universe.
