Above post for everyone.
Some of the names might have got cut off, but I typed in “all”
"All" is nobody. That is to say, no one ever sees it or responds to it.
Long ago, when this forum was being established, it was realized that certain names should be excluded or sequestered from use. That's what was done.
Don't worry about names being cut off, that's just a limit on the "to" line. They all still get pinged.
The best way to manage a ping list is to put it into your home page, where you can grab it from any computer that lets you sign on, and then you can be consistent with your pings.
