The the "Better Navigation" side bar theme (here:
http://wiki.splitbrain.org/wiki%3Atpl%3Atemplates#better_navigation), I've done a customization to have the side bar only show up for logged in users. You can also tweak it so it is restricted to a specific group of users (ie, if you are adding users to a 'verified' group to manually verify users)...
- In the lib/tpl/sidebar/sidebar.php file...
- Add this to the top of html_sidebar() function at the bottom of the file, like so:
function html_sidebar() {
global $USERINFO;
// Only a specific group of users is allowed to see the menu.
if($USERINFO==NULL || !in_array("user",$USERINFO['grps']) ){
return;
}
...
Note: change "user" to whatever group you want to restrict the sidebar to.
