Accessing the FOG from an iphone or computer or iPad often shows a differing list of "unread" posts.@Holmz

Completely off topic (sorry) +30 years ago we had an Irish trainer come out and in a sentence he said "the user account". It took me days to stop laughing
It wasn't helped by me because I keep asking "what do we log into?" and he'd respond "your account".
