<p>The Comments User Column plugin adds an additional column to the “Comments” admin screen.  This column displays the user display name if the user was logged into the site while leaving a comment.  The display name also links to a page where you can view all of that particular user’s comments.</p>
<p>This plugin is mostly useful for sites that have mixed comments from logged-in and logged-out (visitors) to the site.</p>
