The name of the game is Collective Storytelling.

the Rules:

#1 In order to add to the story, you must read it from the beginning to the point that it leaves off (each time you post).

#2 No denying!!! You may not ignore information that has been presented, nor may you have a character change his/her mind, wake up from a dream, or say, "Just kidding," unless it's essential to the plot line.

#3 Wild / crazy / imaginative elements are, of course, welcome, but they should fit the previously established style of the story.

#4 No derailing a story for your own amusement.

#5 You can post multiple times in the same story, but not back to back.

#6 There's no word count or length limit, but each post should describe only a moment and not go on to tell the whole story. That would defeat the purpose of the game!

#8 Anyone can start a new story anytime they wish.

#9 Be kind. Don't send messeges or post threads and criticize someone's writing. That's not why we're here. If someone posts something that doesn't fit, take it as a challenge and try to incorporate it back into the story.
