If nothing else, it's a chance to use my most obscure Jossverse icons.
Posts can be fics, images, meta, or really anything. It warms my flannish heart that Firefly is the predominant property. (The fest covers only projects, perhaps a bit subjectively, defined as "originated by Whedon" so The Avengers isn't included.)
God knows I haven't been writing much fic lately, but I do feel charged up about my contribution(s) (I might post the alternate fic as well.) I note that my least-pathetic hit counts are for stories written for fests. Not this year's Yuletide, though.
However, considering that I'll be writing an unpopular ship in an unpopular context, that may keep the count down.
