The main tab for a contact list contains the following options:

Person list name
The name for the person list. The name must be unique within the current organization.

Active
Specifies if the list is active or inactive. Inactive lists cannot be added to survey to generate invitations. If a list of persons is already added to a survey to send invitation, changing the list from active to inactive will not stop the system from sending the invitation emails.

Person list owners
The users who own the list. See also How to work with tables.
