On Journals? I think that would be easy. ^^

In how it would work, is that I would be the writer and the audiance interacts

Here's how it would work, I end every chapter with a question A, B, C or D and people get to vote what happans next, so if an option like Manny the Meatball's head explodes and that get's the most votes than that is what will happan in the next story.
