The optional exercise "Contributing to a page owned by someone else (slightly more complicated way)" in the GitHub Pages episode could be expanded, to include a more thorough explanation of the task and the motivation one might have for taking this "slightly more complicated" way to contributing to someone's project.

Thank you for this prompt, @tobyhodges ! I'll look into it this week to get oriented and will make further comments.

I am trying to complete my instructor checkout and see this is still an open issue (on Carpentries help wanted), @tobyhodges could I take it over and wrap it up?
