1. Will need a bit more information. How did you add this staff-id?
2. Use the default email domain censor, and change the following line (vB 3.7.2)
File: ./includes/class_dm_user.php
Line: 634
Find:
PHP Code:
if (is_banned_email($email) AND !$this->adminoverride)
and replace with:
PHP Code:
if (!is_banned_email($email) AND !$this->adminoverride)
Not tested. This should reverse the banned email list (thus making it a whitelist instead of a blacklist)
