It shoouldn't be a very complicated one - a simple star rating with a comment box should do the trick. It is important to be able to poderate the ratings before I make them appear on the site (I can imagine, loads of spam ratings will show up)
I want to be able to add the star rating to my posts with a shortcode, it might even appear in a popup window.
There are so many tools to choose from that I don't really know where to start first.
Which plugins have you tried, and which are worth giving a try?
Thanks in advance
