Richard,
I understand what you are saying, but when a simple search with Google or similar turns up the answer, one has to wonder why the poster didn't just do it themselves.
Given that they have an internet connection to access PPRuNe, there are only 2 reasons - laziness or ignorance.
A sticky FAQ with "Have you tried Google" would address the latter.
There are many times when one can't find the answer on Google or a support site or indeed anywhere - these are the occasions when people like yourself are invaluable.
I agree with Mac and Osbo on this one.
To use a motoring analogy, not everyone is a gifted mechanic, but to call in the cavalry before even looking at the handbook is a bit ummm... lazy?
