We'll create fresh WordPress site with Change User installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Change User lets the administrators of a blog log in as any user of the blog.
When the plugin is installed and activated, a ‘Log in’ link is placed under each user on the user administration page.
The link will change the current user and go to the frontpage of the blog.
