The way Sweet Charity works is that fans offer themselves as "Charity Hos" and post goods or services to be auctioned off. Auction divisions include Cloth Merchants, Fiction, Food and Drink, Graphics, Jewelry, Miscellaneous, and Videos. "Cloth Merchants" includes things like knit and crochet as well as sewn items, and "Misc." includes things like beta services, podfic recording, and items like books. Check out the auction list and see if anything strikes your fancy. (I'm offering a LOTRiPS/Actorslash (or original if you like) story, minimum 3000 words.)
If you have something to offer, go sign up. :) They're taking sign-ups and auction entries through 17 January, at 10:59 GMT. It'd be great to get a bunch more Rings-oriented auction items.
The auction itself runs from 18 January through 26 January, basically from midnight to midnight, GMT.
