Hello @jc999

Thanks for posting this in the Canvas Community!

I was able to test this out in my course. The good news is that If your instructor has enabled the anonymous grading settings within the assignment and you have added a comment, your comment will not show your name or any details about yourself when they go to grade it. Instead it will just show that there is an assignment comment added that they can look at.

Hopefully this helps!
