Make the "rating" non enterable/clickable and a function of the average user review like 99.99% of the sites out there. It really doesn't make sense to have both user review ratings (which could be all 5 stars) and then have a "rating" of 0.
And also, concerning this forum, you need to be able to search for matches in Topics only. Before posting this topic, I did a forum search for "Rating" and what came up was 5+ pages of random topics. Searching topics, would greatly improve the forums.
