League rules.

Here are the rules that should determine your in-game behavior and the punishments for breaking them.
-Leaving a game, at any minute, without a serious reason and without having informed everyone results to 1 or 2 warns.
-Disconnecting from a game, at any minute, may result to 1 warn.
-Playing badly (disappointing your captain) may result to 1 warn.
-Intentionally playing badly results to 2 warns.
-Afking in game without a serious reason and without having informed everyone results to 1 or 2 warns.
-Flaming/swearing in game may result to 1 or 2 warns, or even temp ban from channel.
-Abusing !end command to end a game before one of the teams wins, will result to a temp or permanent demote if used by a captain, or 2 warns if used by a game owner. Remember that the !rmk command can be used. If a player disconnects before the 15th minute the game HAS to be remade, unless all members of the team that lost a player disagree and want to continue.
These rules are applied for EVERYONE, that includes captains and vouchers as well. The rules apply for both challenges and simple private games.

And the channel rules.
-Not using english in channel, while there are more than 8 people in it will result to a warn. No exceptions.
-Flaming/swearing agressively in channel won't be tolerated and will result to 1 or 2 warns or even a temp ban.
-Repeatedly !aborting is considered an abuse and is from now on punished with a warn.
-Signing for a game and leaving @ startpick or when the game is hosted equals leaving the game, and will lead to 1 or 2 warns.
-Spamming channel in any way may result to a warn.
