Scenarios: More of a general note, really; I'm fine with pre- or post- DH, or AUs, as long as it avoids my squicks (aka, ignore or work around the epilogue/ginny issue however you want, but please don't say "ginny sux, so harry left the hoebag," etc).
Gift To Give:
Unwanted character/pairings: Umbridge, Voldemort, Fenrir, any of the non-student Death Eaters.
