Today I was a bit lost when I went through my review queue and stumbled upon this case.
You may disagree that the information itself isn't that valuable and I should just reject the edit, maybe. But imagine a case similar to this where the information is valuable.
The review tools let me: Approve, Reject, Improve or Skip. None of these work if I want to inform a moderator to convert the edit content to a comment. I am aware that anonymous users haven't the right to comment.
Then I thought: Maybe a Reject together with a custom message would fit. Another user had the same idea already. But will this custom message be directed to a mod? I don't think so.
In the end I skipped. I do not want to post a comment in the name of another (anonymous) user, because I can't be sure if the information is correct. And I also do not want to convert the initial answer to a community wiki or post a new answer as community wiki. Its clearly only a comment.
In short: How should I react here?
