Right now, the extension only supports several social networks. The code for displaying social networks can be found at components/com_eventbooking/views/event/tmpl/default.php :
Code:
<?php
$title = $item->title ;
$html = EventBookingHelper::getDeliciousButton( $title, $socialUrl );
$html .= EventBookingHelper::getDiggButton( $title, $socialUrl );
$html .= EventBookingHelper::getFacebookButton( $title, $socialUrl );
$html .= EventBookingHelper::getGoogleButton( $title, $socialUrl );
$html .= EventBookingHelper::getStumbleuponButton( $title, $socialUrl );
$html .= EventBookingHelper::getTechnoratiButton( $title, $socialUrl );
$html .= EventBookingHelper::getTwitterButton( $title, $socialUrl );
echo $html ;
?>
