I'm not the only one who isn't (wasn't) linked. On my block.
Either yesterday's post disappeared or I didn't actually write it. I think I did & it was about fixing one thing & then another, so that my new machine is up & running. The Mac people were utterly unable to help & suggested nothing that I hadn't already tried. Even though the router where we suspected the problem lay was 10 years old & long out of warranty, their customer service was happy to help & gave me the clue I needed. I still don't understand why it didn't work & now it does but I don't care. I promise not to be so boring from now on.
