That is a very good point!
That help is quite unclear even to a native English speaker. I did set 
it on our local mailman but it appears that everyone else here at 
Paddys-Hillhas taken Friday off!  Of course I get the reflection(?) of 
my own post but did the others get it? I can't tell.

I will continue to test locally and let you know, but I think this might 
be a non-starter.
