Here's how it works, there is a list of the current Halo: Reach multiplayer playlists, each with a starting score of 10 (even). To play just copy and paste from the last post and add a point to your favorite playlist, and subtract a point from the playlist you like the least. No double posting, wait 5 posts to vote again. Eventually there will only be one last playlist, that is the clan favorite.
