Greasy Fork

There is a script. i am not an owner of it. I did some changes on it with tampermonkey. New version of the script is working now locally on my computer. How can I publish new version of the script here on greasy fork, and other people to use it?

https://greasyfork.org/script_versions/new

// @name script-name fork

But if the original script has not specified license, by the rules of the website it would be deleted on first demand
