FanFiction.Net

FanFiction.Net (often abbreviated as FF.net or FFN) is an automated fan fiction archive site. It was first launched in 1998 by software designer Xing Li, and currently has over 12 million registered users.

The site is split into main categories: Anime/Manga, Books, Cartoons, Games, Comics, Movies, Plays/Musicals, TV shows, Crossover, and Miscellaneous. Users who complete the free registration process can submit their fan fiction, maintain a user profile, review other stories, apply for a beta reader position, contact each other via private messages, and maintain a list of favorite stories and authors. There are centralized communities and forums. In lieu of signing up with a new account, the website allows users to use their Google, Facebook, or Twitter accounts. The site also owns a Twitter account called FictionPress where users of the website are updated on changes and improvements made.

While Fanfiction.net is still prolific as a viable source of fanfiction creation, the site has shown a decline in popularity due to a number of factors such as a lack of updates, an outdated system, rampant advertisements, and restrictions on types of fanworks. Provided by Wikipedia
