How can I exclude authors by ID from this:
<?php
//displays all users with their avatar and their posts (titles)
$blogusers = get_users_of_blog();
if ($blogusers) {
foreach ($blogusers as $bloguser) {
echo '<div class="content-slider-body">';
$user = get_userdata($bloguser->user_id);
echo '<div class="grid col-140">' . get_avatar( $user->ID, 128 ) . '</div>';
$args=array(
'author' => $user->ID,
'post_type' => 'post',
'post_status' => 'publish',
'posts_per_page' => 1,
'caller_get_posts'=> 1
);
$my_query = null;
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
//echo 'List of Posts for ' . user->user_firstname . ' ' . $user->user_lastname;
while ($my_query->have_posts()) : $my_query->the_post(); ?>
