An Audience Type is a way to group users together who otherwise may not have any other commonalities.
On the Admin menu, select User Groups > Manage Audience Types.
The Audience Type List screen appears, displaying all existing audience types. Select the New Audience Type button in the upper right.
The Audience Type Properties dialog box appears. In the Name field, add the name. In the Description field, add a description if necessary.
Use the Require a Match for all object types mapped checkbox if the members should match all criteria. For example, if you map an organization and a job role to an Audience Type, any user that either belongs to the organization or has that job role would become a member. With this box checked, the user would have to both belong to the organization and have the job role to become a member.
Select the Save button to save.
