Because of the nature of my store, I allow comments/ratings from visitors who are not registered buyers. For the regular Wordpress comment system (moderated) if a comment is left, there's a notice that the comment has been received and will be reviewed before being public.

For WooCommerce, there's no acknowledgement that the review worked at all. I noticed this recently because I had a comment that someone left multiple times. It was not spam and I was curious why they kept leaving it. That's when I tested out leaving comments myself as a guest on the site. If there's no name or the email address is formatted improperly, there are warning messages. However, if the comment is successful, nothing appears to happen even though as the site owner I do get notified that there's a comment awaiting moderation.

It would really help if ratings/reviews by guests always received some acknowledgement that the message was successful much as standard comments work.
