Can't see where they are, I can see links to PN reviews which is unsurprising as the Divines pay the bills on pro$$ienet.
Not knocking any UKP links as it will drive more punters to this site and as you said it does show the importance of UKP moving forward but I would be willing to bet my shirt they won't link any negative or neutral ones.
As the links take you to the Review, as well as subsequents comments/discussions, it may be worthwhile for members on here to post any links within that thread for any negative reviews that may exist for that WG.
This way, whilst they link up only positive reports, within these reports would bemembers' links to any negative ones.
