     //Return mark-up of list (can use eventorganiser_list_event for simplicity).
     return eventorganiser_list_events( $atts, $args, 0 );
}

add_shortcode( 'events_excluded_cats', 'innonet_events_excluded_cats_handler' );
?>

Just a note, I couldn't get this to work without adding event_start_after="now" to the shortcode, eg:

[events_excluded_cats exclude_cats="1,12,18" event_start_after="now"]

Without that, I got a fatal error:
PHP Fatal error: Call to a member function format() on a non-object in ...\wp-content\plugins\event-organiser\includes\event-organiser-event-functions.php on line 1093

thanks! Michelle

Thank you for this ! Just a question, how could I use this with [event_board] ?

Thanks,
