First 2 questions. How was your password reset? Unless you let someone else know your password or logged on through a public PC and let the game open no one except you can change your password.
And if your password was reset how are you posting?

Not if he doesn't know the new password. Because you have to enter your old password into the first field when changing your password. He will have to e-mail member services and let them fix it for him.
