My left hand menu in CoRAS is different to normal?

CoRAS is a role-based system and the role dictates what a User can see and touch

Go to the top left of screen and hover over the second from left icon to view your role. If you need to change your role click on CHANGE ROLE the icon immediately to the left of it.
