yes, but I don't dare losing my landline numbers. If I make a backup file of those, then I'll definitely lose the mystery skype links.
Thinking laterally. If the test lady had bust, and all of my contacts were off line by coincidence, (that would be a first) then that would explain everything but for one pal that couldn't see my mini picture. Long odds.
If I try to reinstate individuals, it tells me they are already there -but it gives me the chance at that time to call them, and it works!
