Well its a quick & dirty implementation, so use at your own risk. This template displays the menu at the top of the page and provides an alternative to the left hand side menu.  This works well with small number of menus items.  Updated the CSS to give a flat look and feel to the site.  For a true top menu need to make changes to the JSP Wiki code to treat that as a special list and then render it using specified CSS.
