Hi
I'm not sure if this is the sort of thing you're after but I just built a php-nuke based reviews module (+ stats) that's currently being used on a couple of sites ....
http://www.punterlink.com (escort reviews)
and
http://www.fetishlink.co.uk (mistress reviews)
ICQ/email me (rg [at] 69design [dot] net) if it the sort of thing you're after..
