Welcome to Newest Member Addon

[godarmy]

Found the answer

edit /core/vb/api/user.php
and add another function like this

public function newestmember() {
		$members = vB::getDbAssertor()->getRow('vBForum:fetchUserStats');
		$newuser = vB::getDbAssertor()->getRow('vBForum:fetchnewuserstats',array('userid' => $members['maxid']));
		return $newuser;
	}

and in the Vb5 template put like this
{vb:data newusername, user, newestmember}

Thanks for lynne for inspiration.
