आप would go to मंच या लेखाए and make a new one. Then आप would write the name/rating/genre/sonopisis/characters/disclamer in the first box. THEN, आप would post a टिप्पणी दे with your first chapter in it.
Just sign up for Fanficiton.net, and once आप do, आप can अपलोड stories that you've written in Word and SHABANG! Write a summary, tag the characters and put the rating.
