In file admincp/user.php, around line 1711 is this code:

// ###################### Start moderate + coppa #######################
if ($_REQUEST['do'] == 'moderate')
{

	$users = $db->query_read("
		SELECT userid, username, email, ipaddress
		FROM " . TABLE_PREFIX . "user
		WHERE usergroupid = 4
		ORDER BY username
	");

You would need to modify that query to get the fields you want to display, then modify the code below that to add more columns to the table and display the fields from the query.
