I've heard of people doing a chain story.
One author starts it, then the next adds to it and on and on it goes round robin.
This site doesn't really have that as a mechanism though does it? It would be awesome if there was a way we could have a public chain story that anyone could submit a chapter to, with the owner able to delete chapters that make no sense. It could also maybe work like Unvierses where its by invitation only to add chapters.
I've tried it for the first time by sending my chapter to another author. It's pretty cool and exciting. I wait patiently to see where they go next with the chapter - instead of going in the direction I think.
.
If we had the ability to submit a "Public Chain Story" - what if it followed the normal rules for Universes - they can be set to public or by invitation only.
Then more than one author can submit to it. First to submit is the one who gets the next chapter.
The owner of the story can request certain chapters be removed. If the owner leaves the site they can grant it to someone else. The author of the chapter can also request their chapter be removed.
Then in the comments of the story authors could discuss the general rules of the story world "Okay, talking trees exist in this world" and as long as you all agree that it does make sense then that fits that particular story.
