Inviting members to your team
To invite new members to a team, you must be an administrator of the team. Assuming this is true, navigate to the Members tab on the teams page and click the "Invite Members" button in the upper right-hand side of the members table. Search for the user you are looking for by entering their name. Click the Invite button to the right of their name - this will send the user a notification with an invite to join the team. Once they accept the invitation, they will appear as a member of the team.
