Especially for clan leaders. If you plan on getting you clan into the playoffs. You need to establish a roster of 10 people. Those 10 must be registered and post once in a thread called "playoff roster" which you must post in your challenge forum. If the IP does not match to the person in the battle when battles happen - you will be asked to replace them (even if they are at their "Grandma's").
Please start thinking of your playoff roster, it must be submitted by all teams by August 1st (1 week before the playoffs start).
