i'm thinking this might get me somewhere
<?php
if ($post_ID) {
if ( $last_id = get_post_meta($post_ID, '_edit_last', true) ) {
$last_user = get_userdata($last_id);
printf(__('Last edited by %1$s on %2$s at %3$s'), wp_specialchars( $last_user->display_name ), mysql2date(get_option('date_format'), $post->post_modified), mysql2date(get_option('time_format'), $post->post_modified));
} else {
printf(__('Last edited on %1$s at %2$s'), mysql2date(get_option('date_format'), $post->post_modified), mysql2date(get_option('time_format'), $post->post_modified));
}
}
?>
but i don't know what to change or where to go from there.
