Here's the details:
This is a writing game where you either start it or finish the story.
If I write 1 page. You write 1 page.
If you write 3 pages. I write 3 pages.
Etc...
We'll use Celtx as it's free and common.

*EDIT
I've just finished a two page sketch:
Logline:
Everyone keeps receiving messages except Jerry. He feels left out of the loop. But then he receives a mysterious phonecall that leaves him happy.
Feel free to bend or twist the story however you feel.
