Question

How can I allow users to discuss a page without altering it?

Answer

You can make discussion pages for every page you have. Of course, this is awfully boring, so let's automate it.

Firstly, let's make the function that constructs and displays a link to the discussion page based on the current page's name:

 
  function DiscussLink($pagename,$args) {
    # if the current page already ends in "-Discussion", don't make a link
    if (preg_match("/-Discussion$/",$pagename)) return '';

    # otherwise, generate a link using FmtWikiLink
    print FmtWikiLink('',"{{".$pagename."-Discussion}}","Discuss");
  }

This must be somewhere in your local/config.php. The preg_match line checks if the current page is already a discussion page (to avoid Main.HomePage-Discussion-Discussion-Discussion) and the last line construct a wiki link. Now the function must be referenced in the template:

  <!--function:DiscussLink-->

If you use default template, this directive should be placed between the link to the edit page and the </td> tag.

If you change the previous function to:

 function DiscussLink($pagename,$args) {
    # make a link back to the original page
        if (preg_match("/Discussion$/",$pagename)){
                $posi = strpos( $pagename, "Discussion" );
                $pagename = substr( $pagename, 0, $posi);
                print FmtWikiLink('',$pagename,$pagename);
                return ;
        }

    # otherwise, generate a link using FmtWikiLink
        print FmtWikiLink('',"{{".$pagename."Discussion}}","Discussion");
 }

The function will put a link back to the page that is being discussed (the actual implementation just doesn't put anything).
