This is EmilyF's TrustRating, which is based on both the number of reviews EmilyF has written, and how many other people have voted those reviews as "helpful." It's a way to quickly to determine the value of any single review or reviewer, because it's based on how helpful EmilyF has been to the Kudzu community.
I took a yoga class here last week and loved it. They offer all different levels so anyone can come. They also offer several different classes a day. My teacher was fantastic. Overall a great experience.
