Formats you can run, and how to set each one up
The game pages cover what changes between titles. These cover what changes between formats — a pick-up night, a season, a booked scrim, an open challenge ladder. They compose different parts of the product and they fail in different ways.
10 Mans
Ten people, two teams drawn fresh every match, and a rating whose only job is to make the draw fair.
1 in-depth guideInhouse Leagues
A closed league for one community: the same people every week, a season that actually ends, and standings that mean something.
6 related guidesScrim Blocks
Two rosters, several rounds, one booked session — scored as one thing rather than as five unrelated matches.
3 related guidesChallenge Ladders
No queue and no fixed night — entrants pick their own opponents, play when both are free, and the ladder sorts itself out.

Most communities do, and they compose without fighting. An inhouse league whose match format is a 10-man night is one league with one ladder. A team that scrims on Tuesdays and runs an open challenge ladder for its members is two leaderboards in the same server. Nothing here is a mode you have to pick between at setup.
The pages exist because each format has decisions the others do not — what to rate, what carries between sessions, and what goes wrong when nobody wrote a rule.
