[l0ven0debb]

Hi, is thre any light weight rating system plugin like this?

Some features expected:
an overview of reviewed item,
key points of reviews (value for money, ease of use, etc.),
details of pros and cons,
a rank list can be placed in other area as a widget,

Of course, I'll be happy to pay for it.
PM me, thanks

If I wanted to develop it by my own, what kind of coding knowledges should I learn? Please help.
