It's a place where peeps can write stuff, make icons, fanvids, fan mixes ... y'know anything fanish, for other fans. Then in Jan the posts are unscreened so peeps can see their fandom stockings.
I have just signed up because alyse made all of us at the party promise we would, but my stocking post is not up yet. I will post a link once it is. This post is to ask about other people's fandom_stockings.
