What is User Impersonation?
User Impersonation allows Administrators to access and operate Channeltivity as if they were logged in as that User.
Why is this feature important?
This feature is useful when testing permissions and content that only your Partner Users can see. For example, if a Partner User has encountered an issue while using the system, an Administrator can use the User Impersonation feature to troubleshoot.
How do I impersonate a User?
Go to the "Admin" tab in the left navigation menu and select "Users" from the sub-navigation menu.
Click on the First or Last Name of the User you wish to impersonate to view their Profile.
Click the "Actions" button in the top right corner and select "Impersonate" to assume the User’s identity.
You will then be taken to the User’s homepage, where you'll see a message at the top of the screen confirming that you are impersonating the User. 
To exit Impersonation and return to the system as yourself, click the "Stop impersonating" link at the top of the page.
Who can impersonate Users?
Admin Users are the only Users who can impersonate Users.
Can I impersonate Users using the "Preview page content as..." functionality on the home page?
No, the Preview page functionality only allows you to view content on the home page as a specific User. It does NOT apply to other areas of the portal.
