Quickbeam"I don't know where one get an easily impressed friend from..."
Exactly!! Perhaps this might help to explain?
One joins a forum as 'Graham', then promotes oneself to 'Colonel Graham', then decides a 'one star' rating is required - before being informed there are no such things as 'star' ranks below general, and so removes the 'colonel' (but, bizarrely, not the star!!).
It seems perfectly obvious to me that a picture of a wall safe is precisely what's needed.
