What would be really neat is to have this tied into the download section. So, for every download item, there would be a button "Review (download title)" instead of the rate it button. Then the category and subcategory would be set from the download item. And a further subcategory from the title of the download, since there could be more than one review of each item. Then there would be a list of reviews below the item. And maybe an averaged rating, for each item, from the overall rating of each item.
