How can i add a review useful vote system in magento?

Question

I want to add a thumbs up / thumbs down system to the magento review system and don't quite know where to start. What are the files that control the review and how would I go about extending it to fit my needs ?

Thanks

There is extension on Magento Connect which have similar (actually I guess only wording differ) functionality. You could install/download it and check source. You could check demo here. Note "Was this review helpful?" at the bottom of review block.
