I used to have my fanfiction up on Livejournal (white_serpent), but have deleted the journal. It was also mirrored on Journalfen, but that's been down a couple of years now. My old Slayers fanfiction is still posted on fanfiction.net (under Avocado).
Note: I've set things up so comments/etc are not sent to me, and my email is not posted. If you are trying to contact me for permission to translate or podfic one of my fanworks, this isn't necessary. I don't mind translations or podfics at all, as long as you make it clear that I wrote the story, and, when possible, you include a link to the original. (You can credit me as white_serpent or Avocado; either is fine.)
