Being able to comment would be cool! I don’t think it will happen, though. Hopscotchers could comment bad things and The Hopscotch Team wants to keep us safe.
Also, you can report projects! You just click open the project, click the three dots in the upper left hand corner, and there should be 3 options available: Publish Remix, Save as Draft, and Report. From there it will ask why are you reporting the project, and then The Hopscotch Team will review it!
