Essentially, you post a text thread with the start of an adventure, giving as much insight to the story as you choose. Then as the original poster, you are the DM. Whoever comments, is starting their story as the player/character. The story then unfolds from there. Probably easier to go take a look at it to get an idea and what you'd want to use and what you'd maybe want to add or remove should you choose to create a similar tribe.
Ooooooh sorry it's YouEnterADungeon not You Enter The Dungeon.
