I gave the reporting a try, and I like the flow in the demo (which is for a Public repo); easy to use.
For a private repo, I would probably also want people to be able to leave anonymous replies (to get 'as much feedback as possible'), but that's just my n=1 opinion.
Thanks for the feedback, I have been thinking of whether making email optional or allowing the admin to not show it. Your feedback is a noted data point, thank you!
