This will allow to order a wordpress user query by random.

WP_User_Query Order by RAND

<?php
// put this in your functions.php
add_filter('pre_user_query', function(&$query) {
   if($query->query_vars["orderby"] == 'rand') {
       $query->query_orderby = 'ORDER by RAND()';
   }
});

// Query will look like this:
$args = array('orderby' => 'rand', 'number' => 5);

$users = WP_User_Query($args);

Thank you!

The anonymous function messed it up for me, I used:

function wp_user_query_random_enable($query) {
    if($query->query_vars["orderby"] == 'rand') {
        $query->query_orderby = 'ORDER by RAND()';
    }
}
add_filter('pre_user_query', 'wp_user_query_random_enable');

Hi Guys, Thanks
