All I do is "copy and paste" the Craigs link into an open "new message" form, so you "right click" on the address and select "copy" -----you may need to highlight the thing.
You don't even NEED an "in computer" email program, and it's a LOT safer so far as viruses and bugs
I have email at my primary provider (Time Warner) is roadrunner.com, at yahoo.com, Gmail, and a couple of others I seldom use.
EVERY ONE of these I access online known as "web based email."
My primary provider used to be Adelphia.net, now Time Warner. Even when changing the suffiix from @Adelfia.*** to @Roadrunner.com, I had a certain amount of stored emails online. I "send myself" my bookmarks and email addresses, and that's a handy place to park them. They've been there for YEARS now with no glitches
