Hi,

I have done this in the past with a bit of jQuery. This basically grabs each h2 element with a moduletitle class and then lists those elements in an unordered list above your content. 

<style type="text/css">
#toc .ModuleEditLink{visibility: hidden; display: none;}</style>
<script type="text/javascript">
        $(document).ready(function() {
            var items = "<ul>";
            $("h2.moduletitle").each(function(i) {
                var current = $(this);
                current.attr("id", "title" + i);

                items += "<li><a id='link" + i + "' href='#title" + i + "' title='" + current.attr("tagName") + "'>" + current.html() + "</a></li>";
            });
            items += "</ul>";
            $("#toc").append(items);
        });
</script><p id="toc">
    On this page:</p>

Hope this helps,
