That's really interesting, I'd wondered if that was feasible! A few years ago I needed to send myself notes and URLs from a work computer to look at later, so I put it into the browser as https://< my website >.com/index.html?saveforlater=note%20to%20myself

When I got home I'd search the server logs for "saveforlater" and retrieve my note. Though it might have been faster to just write it on a slip of paper.
