 * Hello!
 * I would like to exclude category from the loop and I have some question:
 *     ```
       <?php if ( is_home() ) {
       			query_posts($query_string . '&cat=-124');
       			}
       		?>
               <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
               	<?php get_template_part( 'content', get_post_format() ); ?>
               <?php endwhile; else: ?>
                   <p><?php _e('empty'); ?></p>
               <?php endif; ?>
       ```
   
 * A guy told me I have to use global $post, posts instead of $query_string, whats
   the difference? I read in the codex I have to run wp_reset_query(); after i “
   finished”? Why? And where have to put that code? (wp_reset_query();)
 * Thank you very much!
