title: How does one alter the sidebar of a MediaWiki site?
body: <p>The default left sidebar for a MediaWiki powered sidebar contains such links as "Random Page" and "Current Events." I want to hide these.</p>
  
  <p>Is there a way to do this aside from using CSS (<code>display:none;</code>)?
  Correspondingly, is there a way to add pages to this list?</p>
  
  <p>Would this require editing any PhP files?</p>
  
  <p>Thank you.</p>
