Sweet Cavey! You going to use this site or make a new one? Sammy, a ladder system is pretty simple. Teams sign up and play. When you beat a team, you move ahead of them in the ladder. You can have different rules for how you handle matches, but basically you can challenge any team above you. So the team in first usually gets a ton of matches. Usually they are restricted so you cannot challenge a team more than say 5 rungs ahead of you. So you have to play your way up. And usually there is a tourney variation of the mod with tourney admin stuff in it. Rules can be that the challenged team picks the server, etc or however you want to make it. I ran a Quake 2 Action Quake clan for a long time and we played on a world wide ladder. Very competitive, lots of matches.
