Sometimes, that epic raid really envelops you and all of your attention into the game, or maybe you've just REALLY gotta concentrate on the latest Sombra clue to find the next step in the puzzle. Discord has 4 separate online statuses that let you pick and choose how you appear to others and keep your focus intact other places if you need.
To change your status, it's as simple as left-clicking your user avatar in the client:
You'll see the status-picker menu pop up. You've got four options:
Business as usual. You'll appear online with a green circle beside your avatar.
Normally, you'll automatically switch to idle if you're AFK for a certain amount of time, but you can manually select it in the pop-up menu. Unlike the auto-idle status, manually setting idle will allow you to stay that way indefinitely.
Setting yourself to Do Not Disturb (DnD) will show your avatar with a red circle and automatically mute any and all desktop notifications you'd normally receive.
Setting yourself as Invisible will make you appear offline entirely, but you'll still be able to access all of Discord as normal. This includes messaging your friends without appearing online. ♪ ♫ Super Spooky Skeletons... ♪ ♫
