The intended users are the authors of fiction and fan-fiction who want to write collaboratively and the people that read them. Most current authors are familiar with the basics of web-based posting, word processing, and Internet usage. A subclass of the authors are moderators, who create and maintain group stories. By default the moderator of the story is the original creator, and as such will set the tone for the style and quality required for a given project. The moderator subclass will probably be more familiar with word processing, though will not necessarily have any more experience using web interfaces. Most users will be younger (high school or in their 20s) and English speakers.
