Adding Teammates and / or Clients is available on plans Company and above.
Top tip: Add your Organisation name before inviting people so they know it's you.
To add teammates and / or clients, head to your Dashboard. From here, click on 'Manage People'.
Next, click 'Invite People' and add them in. Unless you are an Agency, add people as Team Members.
Anyone added to a Calendar at this stage will be automatically given the User Permission of 'Creator'. You can change this permission later on through the 'Members + Approvals' section within each Calendar.
Once you are done, you will see a list of users in the main 'Manage People' area.
