You mean this bit from Tacit?
"Most likely, they know about the Yahoo account because they see the Yahoo cookie."
Well, my F/book account was registered with a Yahoo email address. (Which I've now deleted.)
Hence them seeing a Yahoo cookie. According to your/Tacit's "logic".
You can sneer at me all you like, Hal. It only hurts a bit. Not being believed by anyone here (other than sneering Hal) hurts more.
Oh and before I leave I must say that I really don't like being spoken to like that. I run my own small but successful business and have done for 25 years, through multiple recessions, ups and downs, but we keep going strong. Not many other small businesses can say that, these days. I have staff and legal and financial responsibilities. I am not stupid, nor an hysterical type.
So now I will take the course which is usually advised when encountering someone who takes great glee in trying to pull you down on a messageboard: Ignore Them.
That is my last post to you. Goodbye Hal.
