This addon provides additional functionality to display attendee information.  The attendee information must of course be available in the ics file or in your events inside wp.  The add-on displays participation  status (with icons) and attendee roles (cs roles).    It will attempt to cope with any missing names and missing emails to present a reasonable list.    Css classes are provided to allow you to style the information.   The formatting functions are pluggable should you wish to override them if css options are not adequate.
