There is no means that I know of to achieve this from RH or
any other tool. The help has to be in a location that cannot be
accessed by unauthorised users and that is down to your developers.
I suggest you edit out your email address to prevent yourself
getting spam when the address gets picked up. Also the idea of the
forum is that answers are posted here so that others benefit.
