[Zope] wiki-how to add comments to top of page

Hi, On our wiki we have users entering comments with the comment box at the bottom of the page.. The wiki adds comments on the bottom after the last post. So the users have to scroll down to see the newest post. But with a long list this is annoying. Is there a way like squishdot, to locate the new posts to the top of the page? I haven't found the way to do it. Thanks. J
