During rounds you can select an emoticon by pressing the little speech blurb icon (…) to bring up all sorts of emoticons to use.
Once you select an emoticon, it will display to all other golfers that you are currently playing with.

You can use various emoticons to convey different emotions such as congratulating a fellow golfer or let out a sigh of relief.
Just as it is expected in real golf, it would be frustrating if a fellow golfer tried to interfere with your play.
We gently ask all golfers to observe common sportsmanship and basic code of conduct while playing a game by refraining from "spamming" or distracting other golfers through repeated use of emoticons :-)
