Okay based on your name I'll assume science fiction as a base. Fan fiction comes from your the fan you have a story based on a favorite set of characters, worlds, uni/omi/omega verse and want to either a) alter a key event in the series and diverge from the incoming events or b) continue the series from some leave off point that the author left more or less open.
Now what you need to do is find a fan forum or site and build credibility then from there you start mini blogs with partials. Followed by your grand unveiling into the fan fiction writers of the copyright tracker list. DUDE THAT is a joke. Copyrights around fan fiction are fun look them up and have a good laugh 90% of the time their just plain funny.
So any other help required just ask.
