Forgive my disbelief, but people post fanfictions on here? I always felt that FPS communities were too toxic to actually allow this sort of thing to be posted without berating the poster off of the site. This amazes me more than anything.
Here is a group where fan-fiction writers can interact with one another and work to improve their skills, if you want to be include message me a link to some of your fan-fiction. Here your free to post all your fan-fiction (Just please, don't be inappropriate) and you can also message other fan-fiction masters to have cross over and ect.
