Your forum is closed,so before he can visit your forum, you must add his user name to your approved members' list;then,he can log-in, get on your site and go to My Account;there,he can change his password.
An alternative would be for him log-in to NW54,visit an open site (such as my Hummingbird Forum) and get to his My Account there.
