     You first have to decide on a message, it shouldn't be too long but be long enough to get your point accross.
     Then you have to decide on a sender. The sender is a string by which the different @ref orxonox::NotificationQueue "NotificationQueues" (the entities that display the @ref orxonox::Notification "Notifications") can decide whether they should display the @ref orxonox::Notification "Notification" or not. So the sender is some string that identifies a group of @ref orxonox::Notification "Notifications" that have something in common or some entity that is sending them. For example: All @ref orxonox::Notification "Notifications" sent by any part of the Questsystem have "questsystem" as sender and thus we could create a @ref orxonox::NotificationQueue "NotificationQueue" that only displays @ref orxonox::Notification "Notifications" from the Questsystem, but more to that later.
-    And lastly you have to decide to whom you want to send this @ref orxonox::Notification "Notification". You have to get the clientId of the intended recipient (e.g. trought a @ref orxonox::PlayerInfo "PlayerInfo") or you only send the @ref orxonox::Notification "Notification" locally, either by setting the clientId to Host::getPlayerID() or by setting the variable 'isLocal' to true, and setting clientId to what ever you want, since it will be ignored.
