I got this idea from writing.com
What if we had a story that each member could add a chapter to. These stories can be added onto by any member that wishes to participate. At the end of each chapter, readers of these choose-your-own-ending stories are given various plot choices to follow. When a member comes to the end of a storyline, it's his or her turn to add a chapter!
I'm not shure how we would accomplish that but hey, it was an idea (and its not original )

Prae, you can't do that in a Story, but I believe Daggle C did something like that in the Forums-The Never Endding Story-.
You could try doing a Forum One!

I like the idea.
Instead of having the problem of all the authors stories not mixing that well and clashing you would have a good mixture of action, poetic, descriptive and comical writing. Its a good way of bringing us together.

Well not quite sure I like the idea. Why just add other peoples chapters if you could write your own story?

i like it! it lets you see others perspective of your writing, so you are able to see it in many different ways! thus improving the way you look at things. which is why i think in some ways this is better then writing your own book alone...
