Here's how it will work.
Pre-season: 4 games, 2 weeks to do each games. Officials will decide who play vs who. So you only have to decide with the other team when you play. As soon as the date and time are decided, you have to inform an official about it. Even if it's pre-season, we want to spec every game. The easiest way to contact an official is on gamesnet in #lcs. If your clan isn't on IRC, please, get 1 on IRC before the game scheduled time so you can find servers and ping opponents server.
Single-elimination tournament: After the 4 pre-season game, the tournament begin.
