My fic lives at my Archive of Our Own page. Some of its been posted here, too. But some hasn't, so AO3 is the best place to find most of it.
The majority of it is for Tamora Pierce (Tortall-verse) and Buffy the Vampire Slayer. The rest (right now) is Tamora Pierce (Emelan-verse), Angel, Firefly, Across the Universe, and Catherine Christian's retelling of Arthurian legend.
Sometimes I have Tamora Pierce fic (both universes) at the Goldenlake message board before I bother to archive it.
