Here's an example; http://prntscr.com/an3d90
As of recently, I've been seeing a lot of automated messages appearing in the chat. For example, admin scripts sometimes display "This game is using blah blah blah" in the chat when you first join a game.
I'm simply looking for a method, or I'm wondering if anybody could link me to a wiki page if there is one regarding this.

Color3 values are floats so it should be Color3.new(255/255, 255/255, 255/255)
Why place in StarterGui? Put it in StarterPlayerScripts and don't make it a function, so it doesn't take up memory parsing when it's not necessary.
