"While browsing I came across a comment from an author saying he would never post a partial story again, he would always wait until the story was finished before posting in future."
The author who said that was me. I hate reading stories that leave you hanging. If the story if nothing more than a sexual encounter or a snippet of a scene (like some of Fox's very short stories), then an open ending is not really a problem, but if it is a lengthy story with well-developed characters and there are conflicts that need to be resolved and a real plot, then it is irritating to be left up in the air. There is a deifference between a deliberate open ended conclusion and a sudden stop in the story line. I have been guilty of the latter with one of my stories. As they say, Do unto others ... I feel badly about leaving my readers hanging.
PS I am still working on Chantelle.
