As of right now, anything goes (as long as it's R/L, of course). Fics, Artwork, essays, anything can be submitted and it doesn't matter if it's been published before! We want it! Winners will likely get posted on our site (I got a button made!) and the LJ.
So if you're interested, go to the forum I linked to above. There's plenty to do while you wait. :)
