Rating Stars are a nice enhancement to your reviews.
There are a lot of plugins out there that provide ratings for your sites but they pull the information from social networks and you don't have control of the rating. The rating becomes a conglomeration of Google+ ratings, Yelp ratings etc.
I like to let people know how I feel about a product without allowing others to control the ratings.
In this tutorial, I have outlined how I include rating stars on my posts.
I have referenced this site: http://testsite.siterubix.com/rating-star-demo-post
You are welcome to go to it and download the star images from the post for your use.
At the bottom of the page, I have included a pdf file. You can copy the code from here to use on your own site if you choose.
Another one bookmarked, I know I will need this in the future. Very many thanks,
All the best,
Brandon
