This is swanie's TrustRating, which is based on both the number of reviews swanie 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 swanie has been to the Kudzu community.
They come right out, are reasonably priced (and I mean that), and are so professional. They're always helpful too, answering all our questions and suggesting ways we can even save money. Highly recommend them.
