I have my blog on GitHub Pages with Jekyll. The .md files are in a public GitHub repo. I would like to be able to add a link at the bottom of a post, something like "Feedback? Suggest changes at
link". This link would go to an interface that non-technical people can use to edit the .md file without an account. Bonus points if it can submit their changes as a pull request. But any way of storing the changes would be fine.
I've already tried to make this work with prose.io and stackedit, but it didn't work.
