Show total user count on website?

If I go to Reports, and Count user signups, it displays a total number of signups. I would like to display this number on the front end of my website, where anybody could see it.

I know how it was done in v3, but I'm clueless on how to do it with v4.

I know how to have it display my signup's username, email, name, etc., on my website. I'm using this code:

<?php
require_once '/path/to/amember/library/Am/Lite.php';
echo Am_Lite::getInstance()->getUsername();
?>">

What code would I use to display the total number of signups in my database (expired, paid, and free)?

I'm wondering about this as well. Was this ever resolved?

Thanks.
