July 1, 2009 was a red letter day for residential contractors in Connecticut. The Nutmeg State adopted a protocol that eBay, Amazon, and others have used for years. These Web vendors make it easy for customers to know who they're dealing with. eBay calls it their "Feedback Profile." Click the link and you'll see ratings and comments about a particular vendor. Starting July 1, Connecticut requires about the same thing – but not on the Web. Connecticut wants a feedback link embedded in residential construction contracts.
