I write fanfiction in my free time, mostly crossovers, but sometimes purely of one fandom or another.
There's an open invitation to all comers: interrogate my text from a different perspective. My sandboxes are open to anyone who wants to play: be they remixes, sequels, missing-scenes, vignettes, meta-commentary, what-ever-crazy-fan-thing-it-is-you-do. I think fish_echo and others better versed in meta would say that the blanket term is "transformative works," or I may be abusing that term entirely. All I ask is for you to send me a link to see it so that I can ooh and awe or potentially tilt my head at it appropriately ('Dean slashed with the tentacled demon from the UU courtyard? Oh, and look, the author included helpful diagrams.').
I'm sometimes slow to archive when I join a new site. In general, my master fic list at LiveJournal will have the most recent updates and listings: [Master Fic Link]. Except when I'm particularly lazy (like right now), and the most recent listing can be found at my delicious account: [Link to Delicious]
