I want to add this url: https://pastebin.com/g7V2Q4nX#bZgTqBHM to my post Outfox Semiconductor's FPGA Source Code Is Now Under the GNU GPL Version 3, how do I do that?
If you want to post a link, just post a link. The #1 noob mistake for posting on HN is that somebody feels they just can't post a link so they start a discussion and <i>then</i> they find out the URL can't be clicked.
I suggest you create your code in GitHub or GitLab and separate that long pastebin in three files: README.md (explain Why and What this is, add your gofundme and other comments), LICENCE file and actual code file.
