Everyone can play, it's a simple game.
Here is how: Somebody posts a word and the next person has to post another word that starts with the letter that the last one ended with. You may not use plural words though, or else everything will start with an s. You may not go 2 times in a row, so if nobody is on you can only post in this thread once.
Also try not to repeat words or quote others.
Example of the correct way to play:
Person 1: Cheese
Person 2: Elephant
Person 1: Tape
Person 3: Enchilada
