Talking

[vietbound11]

In servers when admins talk it shows up as "Admin: Hello everyone"
in green.
How do i talk like that so when i talk it shows as green or hides my name, also i want to hide the text of my commands.
Like if i want to slap someone, i dont want it to say "Your Name" Slaps "Player1" 0 damage.
Can i hide all those text?
Thnx

That's an admin option.
