My original e-Mail address was generated at a long deceased Web Service Provider (Dial-up) many moons ago in the 1990's.
Since then they have been taken over by various companies, but, luckily, I have still been able to retain my original e-Mail address...

...!
I still use it daily, and everyone who needs to know, knows it.
My constant nightmare is that my present E-Mail provider will close my original (free) account, and insist that I use their latest Web name in my address!
That would put an end to my universally, well known, E-Mail address!....
