Retrieve total number of users

Hi guys,

i need to add the total number of users in the EasySocial Users module. I'm editing template override from it in /templates/mytemplate/html/mod_easysocial_users/timeline.php, tried several codes but i always get error, and the help doc doesn't provide the info on retrieving the total number of users. I just need to echo the number of users. Can you help me out with this? thanks.
