Hack available for Review site?

[kma]

Hello,

I was wondering if there is anything available (or even possible) to allow vb to have forums dedicated to reviews of various products?

I'd like to switch over my website to be forum based. In addition to having "normal" forums, I'd also like to have a section that allows visitors to submit reviews of products. This would require me to change the way the forums in those particular sections work so that the user has new features (like ranking the products attributes in different categories: 1-10) and state opinions about the products. I'd imagine the thread would be locked after the initial post (review submission), but could be read by other visitors. Also, I'd like a way to tally up the rankings and keep global totals for each product. Would vb allow for this type of modification? How difficult would it be to do? Is there anything similar available?

Thanks for all of the help!
