WP Users Masquerade

Allow WordPress administrators to masquerade as other users on their site. Adds a dropdown select box to the admin bar as well as individual links in the dashboard’s user view. WP Masquerade also allows the user to revert back to their previous session for easy return to the admin user.

Thanks to JR King (castle-creative.com) and swingline0 for the initial development of the plugin was forked from.
