AWESOME plugin by the way :o) I voted 5/5 for it :oD
I have a suggestion... Sometimes on my blog, people vote 1/5... This frustrates me because I have no idea why they've done that.
It would be really good to have a tickbox to have a popup forcing people to put a comment if they give a star rating of less than or equal to(say...) 2/5. It would be good if the comment would come up as a WP Comment (so it can get picked up by people's comment spam plugins and be handled as the website owner wants their comments to be handled).
Thanks again for all the effort! Best rating plugin eva! :oD
