My parents had a QLink account back in the mid late 80s that I sort of had access to.
Then they ran a BBS in Tacoma for a couple years in the early 90s (this is how I ended up meeting the first girl I had a crush on, she was daughter of some BBS person my parents were friends with, fucked up people they were).
Uh, then we had AOL and Prodigy around the same time and I know my parents had had Unix accounts before that. I got my own personal AOL account around 96. My current Yahoo email address dates back to 97.
So yeah, that's about it for the early years.
