Writers may upload their stories to the site and assign them a category and rating (such as K, K+, T, and M). The ratings are no longer done on the MPAA system, due to cease-and-desist demands from the Motion Picture Association of America in 2005. A list of explanations for the rating system currently employed is available from the drop-down rating menu in each of the individual archives on the site. The MA (18+) rating is not permitted on this site. The site does not pay money to people for posting content or charge money for posting on the website, and it uses advertisements to pay for costs.
