jRating is a new cool plugin for creating an AJAX-powered rating system.
jRating looks cool, and can be integrated seamlessly with other plugins, such as jNotify, as was done in the demo.
Its options are quite vast: you can disable the rating, save the ratings, set the amount of stars, allow decimal rating, etc.
Perhaps the hallmark feature of jRating is the option to “fill” the rating stars by parts, because users don’t get to see that every day.
A thorough plugin–definitely a keeper.
