The page you're talking about is not the Forum, is the Discussions page. New wikis have discussions and not forum, Special:Forum redirects to Discussions on new wikis. Unfortunately, you can't make the page look like the Forum. However, take a look at this page for admin and moderator tools in Discussions.
