When you SHOUT something, you project your voice across the land to any that can hear it. SHOUT <your message> is the syntax, once you learn Recognition in Discernment you will be able to see who is shouting, and those with it already will know when you are shouting.. The other mortals will simply hear something like "A weak and feeble voice shouts, 'Aaarrggh! The rats! They're everywhere!!'" or, if once you become stronger, something like, "A powerful female voice shouts, 'Aaaarrggghh! The dragons! They're everywhere!!'"

Generally speaking, if you want to speak to an individual player, it's best to use tells rather than shouts. Further, to reduce unwanted spam from a potentially valuable channel, insulting other players, or gloating over them, is prohibited on shouts.

As you progress in levels, you'll find that your shouts change. Further, once you are ranked in the top 40 players, your shouts will automatically include your name, so that all will know the power of your will.
