Manage > Management Dashboard > (Your Network) > Members > “Proxy As User” row action
The ability to proxy as a user is a powerful tool for assisting users and troubleshooting problems.
This tool allows a manager to temporarily log in as another user to see from their perspective while interacting with the site.
While proxied as a user, everything you do will be as if that user has done it, so be cautious of any changes you make.
Be sure to remember to log out of the proxied account before closing your window, or you may still be logged in as the user when you return to your site!
