If you want specific usergroups only to see a navbar tab, then create a plugin hooked at "gloabl_bootstrap_init_complete" with code like this:

PHP Code:

global $vbulletin;
$show['mynavtab'] = false;

if (is_member_of($vbulletin->userinfo, array(groupid1, groupid2, ...)))
{
    $show['mynavtab'] = true;
} 


Where I have "groupid1, groupid2, ..." you want to put the comma delimited list of usergroups by id that you want to have access to the tab.

And then in the Navigation Manager, in the field labeled "Show Permission Name" put:

mynavtab

You should use your own name for "mynavtab" that indicates the nature of the tab. Make sure they are the same in the plugin and in the Navigation Manager.
