The purpose of this trial is to find out if a special website might help people discover if they have high cholesterol and then enable them to manage their cholesterol more appropriately. The primary aim of this trial is to determine the effects on consumers' use of cholesterol lowering therapy of an online service that provides automated, individually tailored, advice about eligibility for cholesterol lowering treatment. The primary null hypothesis being tested is that the service will result in no change in the use of cholesterol lowering treatments by consumers that use the service.
