Rating businesses is simple - but you first need to sign up for an account on the guide.  If we didn't do that, people could easily stack all the ratings, so we ask that you register and let us know who you are before you rate businesses. We don't ask for a whole lot of information, and we promise we will never sell it or give it to anyone (with a few legal exceptions - but you can  read the privacy policy when you sign up.) 
Every business has a link at the bottom of their full description that you can click on to rate the business. Be fair, but be honest.
