Rating and reviews of documents

I am helping a teacher resource sharing site, and we are looking for a plug in that will allow members (using S2members) to rate (stars) and review (comments) each individual document. We expect quite a few documents to be uploaded, and want to help teachers find the "best" resources quickly, and also to provide feedback to authors, providing suggestions for improvements.

I haven't been able to determine if this feature is available. Is this possible with WP File Download?

Thanks.
