Labels are tags used for categorizing your announcements. You can categorize and search for a specific group of announcements by giving them labels.
If you've got lots of related announcements, you can use labels to group them together depending on their category. Users can search and filter announcements by those labels easily.
You can add as many labels as you want and they will appear both on your widgets and in your feed.
How to manage labels?
You can add new labels, change their names and colors, and order them as you wish by going to your Settings and then Labels.
