To allow your readers to Filter Content based on their Preferences, they'll need to be added to a Topic.
You can Add Topics to your Sign-up Form to give employees the opportunity to opt-in to a Topic, or follow the instructions below to add your People to a topic manually using a Search.
To Apply Topics to your People using Search:
In the People area of your account, select Search from the menu on the left.
Run a Search to target the People you'd like to apply a Topic to. All the People matching your search criteria will be displayed on the results page. Use the checkbox beside each employee email to choose the ones you'd like to add to a Topic.
At the bottom of the results, select the Topics button.
Choose the Topics you wish to add to your People and click Save.
Note: You can also Remove Topics from your People here.
