Apologies to everyone on my mailing list, I sent out a “newz from julz” update to you this morning, and whereas there was a facility on my old computer system, Mountain Lion, to hide all the addresses in a group, which I aways used, and I assumed it was the same with Sierra. (see Digital Nightmare!)
However, it seems they work on the basis that if you start a new group, you can decide then whether the email addresses in the group are available to everyone who gets it, or to keep them private – but there is no way to do this with a group already put together!
I couldn’t find a facility to do it any other way, and thought that because the old groups were already private, they would stay so!
I just got a “remove” email from someone, and the whole list of recipients was on it!
I got a real shock!
I promise you I won’t let this happen again, even if it means having to enter each separate email address into new group!
I really can’t apologise enough – but I honestly didn’t realise what was happening!
UPDATE – on 4 Sept: The problem has now been resolved – please see
