I would like to chime in with the same question.
It *could* be a good plugin, but in the current version it’s just useless to me:
– no language files (not the entire world speaks english)
– no template / css customization
– very limited scope with custom fields
but it has some really good features, like the differentiation between product / business ratings, moderation capabilities etc.
I (and I think many others) would be ready to pay for a better pro version – and there aren’t really many other plugins around that do the same. it’s a shame this project has stalled.
So please, give it a go!
