The easy way to only allow administrators would be to edit quotes.php

Find

PHP Code:

require_once('./global.php'); 


and after that add

PHP Code:

if ($_REQUEST['do'] != 'view' AND $_REQUEST['do'] != 'list' AND $_REQUEST['do'] != 'rate' AND !empty($_REQUEST['do'])) {
    if (!$vbulletin->userinfo['permissions']['adminpermissions']) {
        print_no_permission();
        exit;
    }
} 


Restricting the quotes to various usergroups is something I'll work on for the next version.

EDIT: For those of you having problems, what exactly is going wrong? What shows up on your forum home page? What happens if you go to quotes.php?
