As far as i know...Pool admins cannot change or retrieve your PINS....the CAN unlock the accounts....but passwords and email addresses and PINS are up to the users to be responsible enough to remember or WRITE DOWN....not trying to get in a fight for MineBIG....but it sounds as if you need to take better care of your passwords...
