Here is how it works.
The member that posts has to make a sentence and leave out a part where another members name can fit in. Trick is next person posting's name goes there and he has to copy/ paste it and continue.
Example: There once was a kingdom ruled by _______
The next person "Angel"

posts next so it would read :There once was a kingdom ruled by "Angel". and she continues the story.
Here goes:
There once was a kingdom ruled by _______
