The spawnzone system is now enabled for the president as well. This means that the president will have spawn protection as long as he stays in the yellow zone, and you're not allowed to kill him when he's in that zone. If he's still there after 1 minute has passed, the zone will get disabled and his spawn protection will be removed (as well as anyones spawn protection that was in the zone). You're allowed to kill him from that point on. After he's dead and the next president spawns, the zone will be re-enabled.
I'll add some messages to remind the pres to leave the spawn before that.
