aka; Those who dont read rules, just rush into game to grief and whatnot.
This is not an original idea, Ive seen it elsewhere months ago, but I thought it was worth mentioning.
The basic idea is: When you start the game, in /rules room, one of the signs says to shout "zergling" (random word..") This wouldnt be the last sign, it would be randomly in the middle, to prove they were actually reading the rules. This would trigger an event to tp them from /rules to /spawn, but could only be done once. This would allow everyone to see when/if the new person actually read the rules to the point where the hidden exit phrase was listed and reward the new player with praise in chats because they actually read the rules for once, instead of just sprinting to the last sign and doing what it says.
(My evil side says, have the last sign give a fake command, to publicly show they in fact did NOT read the rules leading up to it.)
