At the top of each post by members there is a number (I think that is the number of posts in the thread), right next to that there is a scale. Click on the scale and you can say approve or disapprove a post. I have not put in comments but you can do that too. Not sure if anyone can read a comment or not. Would think you could since it is there.

Thanks anout the icon. I wish they would get more. I love so many different things, like a pretty rose or something.
