A Private Message to a Player.
Used by typing
in your Chat Panel.
To send a /tell in response to a previous /tell, you can use /r, /reply, or the backspace key and omit the name from the command.
You can send a tell to a player on another server by prefixing the server name (e.g. werner.playername). You can also communicate between SOE games by prefixing the game (e.g. swg.playername for StarWars Galaxies and eq2.playername for EverQuest 2).
