Fanfiction.net
Fan-fiction archive website (often written as fanfiction.net or FanFiction.net, and abbreviated as ff.net or FF.net). The contents encompass numerous media fandoms, including Daria. Many Daria fans post their material here and nowhere else, despite the website's restrictions on content and format (e.g., no scriptfics). The site also includes Beavis and Butt-head stories that occasionally feature Daria in her Highland days. Stories are rated by their adult/erotic content, with "M" stories (for mature) being automatically excluded from view using the normal methods of reaching the webpage. (The link below gets around this restriction.)
The earliest Daria story currently posted on FF.net is from November 22, 1998: "Her, Uh, Cane," by Paperpusher.
