"trusted user" expanation please?

Hello world,
I have designated a fellow pvoutput member as a “trusted user” to view one of my sites. But how exactly do they view the site?
Must they search in the long list of live sites? Is it easily visible elsewhere in their account?
i’m a newbee to this, folks, thanks
