Does anyone know how to create a widget for the network dashboard - not the subsites? I tried:
wp_add_dashboard_widget( 'dc_network_dashboard_my_function', 'My Function Caller', 'dc_wp_network_dashboard_my_function' );
but it doesn't show. I tried diving into the /wp-admin/includes/dashboard.php file, but it doesn't give a clear picture of what to do for network-dashboard activation.
