...the other player who send a teleport request is in a world which is defined in the config for example: player1 is mining in main world, then another player2 which is in pvp world sends him a teleport-request, when he accept player2 will kill player1 because he didnt know that player2 is in pvp-world so when someone got a request by a player which is in pvp-world (configurable in config) he gets a warning for example like this: &cAttention! <playery is in <worldname>. or maybe a configurable message for that would also be nice^^ thanks
