I'm trying to not show meta for an author based on is not user_nicename. The code below only works if there is just one user - how would I add another user to the code, so their meta is not shown as well?
<?php if(get_the_author_meta( 'user_nicename')!='user1') : ?><div class="author clearfix">
<div class="author-gravatar">
<?php echo get_avatar( $post->post_author, 64 ); ?>
</div>
<div class="author-about">
<h4>
<?php if(get_the_author_meta( 'first_name') != '' && get_the_author_meta( 'last_name') != '' ) : ?>
<?php the_author_meta( 'first_name'); ?> <?php the_author_meta( 'last_name'); ?>
<?php else: ?>
<?php the_author_meta( 'user_nicename'); ?>
<?php endif; ?>
</h4>
<p class="author-description"><?php the_author_meta( 'description' ); ?></p>
</div>
</div><?php endif ?>
