A lad at work left his email open on the communal PC's. So me being me, had a look around, considered signing them up for some crap n spam, but chose to send myself an invite instead! lol
I emailed him, telling him he could have come off a lot worse! My email was the same name as I had on AOL (back when you paid per minute for internet, and as AOL was a free phone number, I thought sod it!).
So (in theory) I've had my email address for well over 20years.
Back in the day, it was googlemail.com too. I remember getting pissed off it was so long, but then again, most non USA email addresses, had .com/UK on the end of lots of them, or firstname.lastname@example.org, so wasn't that bad.
