Do whatever you want Homeguard, I'm sure you are instructor-something-somewhat-somewhere so you know things better than me.
But I'll keep doing things by the rules.
And when I'm not sure of the rules, I just write to the authorities to make things clear, and I do not try to invent or interpret them.
That's the way it works for stupid frogs like me !
Discussion over for me, useless I think... I wasted too much time !
Good luck !
