Welcome to Newest Member Addon

[godarmy]

Hi,

Can anyone know how to add Welcome to Newest member greeting in template ?
I got the function in core/includes/functions_databuild.php

function build_user_statistics()
{
	$members = vB::getDbAssertor()->getRow('vBForum:fetchUserStats');

	// get newest member
	$newuser = vB::getDbAssertor()->getRow('vBForum:fetchnewuserstats',
		array('userid' => $members['maxid']));

	// make a little array with the data
	$values = array(
		'numbermembers' => $members['users'],
		'activemembers' => isset($members['active']) ? $members['active'] : 0,
		'newusername'   => $newuser['username'],
		'newuserid'     => $newuser['userid']
	);

	// update the special template
	vB::getDatastore()->build('userstats', serialize($values), 1);

	return $values;
}

but how to add it on template system?
can anyone guide me?spending many hours to search it and not found it...
