My first web usage was via message exchange with a local BBS which did UUCP e-mail exchanges every 4 hours. I e-mailed my request to an e-mail <-> web gateway at CERN, and got my page back in the next exchange.

Thankfully that only lasted a year before I got proper access.

And yes, I remember FTPmail, as well as similar gateways for Gopher, Veronica, Archie, WAIS... I feel old now.
