No raging, be a team player, use your mic (or at least be aware enough of your surroundings to get along without one.
This group was created to give people a way to find other good players in Left for Dead. Primarily, people that are good team players, don't rage quit if things aren't going their way, and most of all have fun realizing L4D is just a game.
This group is also a way to coordinate and schedule friends list only games.
