PS. Is RISC an OS?
In the UK it is

Although I am well aware that it originated from a processor design concept (Reduced Instruction Set)

I guess we agree to disagree.
Actually we don't

You are not going to change my mind on this subject... having a policy IS a best practice!
Absolutely, totally, utterly, unequivocally, .............(can't be bothered to get my Roget's Thesaurus), CORRECT!

My "arguments" as you probably see them, are not based on best practice..........rather:

1. We have an existing situation
2. The country and culture are not our own.
3. "When in Rome, do as the Romans do"

In other words they are more "observations"
