Everyone on your team is one of three things: Full access, Roster only or Archived. You change it in Manage Team.
Full access: can sign in and use MyOps. This is a billed seat.
Roster only: on your team and in every report and the leaderboard, but no sign-in and no charge. A Roster only person is always an Agent.
Archived: no longer on the team. Their records stay.
Open Settings, then Manage Team.
Find the person. The list has three sections: Full access, Roster only and Archived.
Open the row's ... menu and choose Move to roster only or Give full access.
To archive someone, choose Archive and transfer ownership, pick who takes their listings, contracts and other records under Who takes the account?, then click Archive and transfer. Archived people can come back: choose Return to roster on their row.
You can also click Edit on a row and change Access for this team member there, together with their role and permissions.
Owners and Global Admins. Admins can add Agents.
