There is a report product button, but since each product can contain 100s or 1000s or reviews if a site is popular enough, there should be a report a single review of a product as well. Right now there is only a report product link.
It would also be cool if each review had the ability to be linked to, much like how replies to threads can be linked to in
VB, where it's the only post on the page. Perhaps with that review using the header and footer to show banners or logos and what not. That way people could write reviews and link to their review directly. Who could spiffy it up and still show the product details/description/images above the review if the admin set a setting for it.
