I think I have a good idea
There is some concern that PPRUNE is too much of a public forum to aire our dirty industry linnen on. To an end this concern is justified, and maybe there is a way to solve this dilema.
As PPRUNE is a forum for industry employed people and enthusiasts alike, it should be accessable to both, whilst the general public need not know aobut everything we do or think, to the industries detrement.
I suggest that some forums that pose these concerns could be not made available to anyone but approved users (as are some forums already). The clincher here is that a simple one off test could be employed to ascertain whether a person is industry based, thus allowing them access.
It would be simple to make up a short test that could differentiate even aviation novices from non aviation people, may need as few as five questions, and could simply be based on something dear to all our hearts....ACRONYMS!!!!!
This is just a thought, but it may well have some merit!!
