Team-taught modules will often require more than one lecturer to edit and add items to the same list.
Fortunately, it's easy to send out editing permissions to everyone in your teaching team. To do this, go to edit menu at the top of the page and select 'invite list publishers'.
Then enter the university email addresses of each member of the teaching team.
The invitation can be sent to multiple email addresses at once; just separate them with a comma.
Your colleague(s) will receive an automated email and must click on the link in that email to accept the invitation to edit the list.
