You can see the CMS through someone else’s eyes using the impersonate feature. This tool lets administrators mimic the experience your clients will have when they login. It’s also very handy for troubleshooting.
To impersonate a client, just select the Impersonate button from Users > Edit.
Everything you do while impersonating a client is on behalf of their account. That means if you publish a page while impersonating someone, the associated revision will have their name on it, not yours.
