title: Get the list of ten top publishers in database
body: <p>I've got following tables in my MySQL database:</p>
  
  <blockquote>
    <p>USERS</p>
    
    <p>iduser nick password</p>
    
    <p>ARTICLES</p>
    
    <p>idarticles iduser text</p>
  </blockquote>
  
  <p>How can I get by one SQL query the list of e.g. 10 top publishers of articles ordering by the count of added articles? Is there any way to do that? I'm using PHP to ask database. </p>
