... Actually, would it be easier to use PRs than work through this thread?

Yes, it would. If someone follows the links to https://github.com/hnpwd/hnpwd.github.io and decides to create PRs, they are very welcome. But if that is too much friction, I'd rather have the links posted here than not shared at all. In that case, hopefully I or someone else will make the code changes to add the website to the directory.
