i adjusted it slightly one less line of code and shows a different message if username not found instead of viewing main index.

PHP Code:

    case 'getinfo':
      $userid = explode("=", $userinfo[location]);
      $username=$DB_site->query_first("SELECT username FROM user WHERE userid='$userid[3]'");
      if (!$username[username]) {
        $userinfo[where] = "Viewing Profile of a Forum Member";
      } else {
        $userinfo[where] = "Viewing Profile of <a href='member.php?s=$session[sessionhash]&action=getinfo&userid=$userid[3]'>$username[username]</a>";
      }
      break; 


No real difference just one less line of code.
