Despite a few tricky settings to navigate at first (finding out how to link the mailchimp to optin rev.) I woud rate this app very highly for 2 reasons. one being the instant impact it has on your newsletter subscribers and secondly for the almost instant support received from the producers. It was missong a particularly important feature, which was added within 2 days of me posting on the support forum. This is very valuable when dealing with live sites. Thanks.
