The function below can be copied and pasted into the skins.php file you wish to modify, after the following:

       function initPage( &$out ) {
                SkinTemplate::initPage( $out );
                $this->skinname  = 'monobook';
                $this->stylename = 'monobook';
                $this->template  = 'MonoBookTemplate';
        }

Make sure the function is part of the first class in the skins file, the one that extends SkinTemplate.

Code

 function buildSidebar() {
                global $wgLang, $wgContLang, $wgUser;
 
                $fname = 'SkinTemplate::buildSidebar';
 
                wfProfileIn( $fname );
 
 
                $bar = array();
        $lines = explode( "\n", wfMsgForContent( 'sidebar' ) );
        if($wgUser->isLoggedIn()){
            $lines2 = explode( "\n", wfMsgForContent( 'sidebar-internal' ) );
            $lines = array_merge($lines, $lines2);
        }
                $heading = '';
                foreach ($lines as $line) {
                        if (strpos($line, '*') !== 0)
                                continue;
                        if (strpos($line, '**') !== 0) {
                                $line = trim($line, '* ');
                                $heading = $line;

                                        $link = wfMsgForContent( $line[0] );

Notes

• Because the sidebar changes depending on the logged in status of the user, caching for the sidebar has to be disabled. This is a small performance hit, and one that should not be noticable on any but the most active sites. If you have been using $wgEnableSidebarCache or $wgSidebarCacheExpiry, these settings will no longer function for any skin utilizing this sidebar.
