Protagonize is a creative writing community dedicated to writing various forms of collaborative, interactive fiction. One author writes a story, and others post branches or chapters to it in different directions. The result is an organic, evolving story where everyone can participate.
Protagonize lets you explore your inner author: simply read and be amazed by the creative prowess of other writers, subscribe via RSS, or contribute to stories yourself. Registered members get their own author profile page, can write new stories, branches and chapters, add page markers, keep track of their favourite authors, add comments, rate stories, participate in (and operate their own) groups, and more.
