Add your team and choose their access

Only the organization owner sees Invite Member. Everyone else can open Settings → Team, but the invite button is not there.

Steps

1. Open Settings, then Team. The page says it is where you manage your organisation, team access and email reply settings. That sentence uses the British spelling "organisation".
2. Press Invite Member. The dialog is Invite Team Member, and it says it will send an invitation to join the organization.
3. Enter the email address. The box shows the example colleague@example.com. Press Send Invitation.
4. The toast is Invitation sent: "An invite has been sent to" that address. The email is headed You're invited! and the button is Accept Invitation. The email says the invitation expires in 7 days.
5. Until they accept, they sit under Pending Invites with a Pending badge. After they join, the badge on the team list is member. The owner is marked owner.
6. To take an invite back, cancel it on Pending Invites. The toast is Invite cancelled: "The invitation has been revoked."
7. To remove someone, press Remove. The dialog is Remove team member? and says they will lose access to all organization websites. Press Remove. The toast is Member removed.

The owner can hand the account over with Transfer, under Transfer Ownership. The line under it says "Transfer organization ownership to another team member." That button only shows once someone else has joined.

If it doesn't work

If the invite fails, the toast title is Failed to send invite. If cancelling fails, it is Failed to cancel invite. If removing someone fails, it is Failed to remove member.

If Invite Member is missing, you are not the organization owner. Ask the owner to send the invite.
