This can be done by adding a string of up to 4059 characters after the "/edit" with another slash, like, to go to the page test, and they could have edited from there. (This already has been stated in the basic /edit paragraph) It was removed when the website went back up in August 2018, after a few years of service, which had a lot of things going on in Edit the Text in it's timeline.
