How do I give a user permissions/access to individual calendars?

Answer:

If you are a user with the appropriate authority (Admin, Parent Calendar Admin, Editor) then you can give permission(s) to users on a per calendar basis by doing the following:

• Click your name/picture in the top right corner

• Click Account Admin from the dropdown menu

• Head to the Team Members section found in the top left

• Hover over their name and a View/Edit Member link will become visible.

• Click the View/Edit Member link 

• Select the appropriate role for each calendar 

• Click the blue Assign Roles button at the bottom of the overlay
