How do I turn on Do Not Disturb?

There are two (2) ways to turn Do Not Disturb on/off.
The first way will turn it on/off immediately. Click the gray circle next to your profile picture at the top right of the page. It has a bell with a line through it. When DND is off, it is gray and a hover message will tell you it's off. When DND is on, it is blue and a hover message will tell you it's on.
The second way is to schedule DND times.
Click your Profile picture.
Click My Profile.
Click the Do Not Disturb tab.
This tab will allow you to set a scheduled DND for specific days and times. You can set a recurring DND and not have to worry about doing it manually by changing the days and times.
Click Save Changes.

Hey, we all have times when we need to be focused!
