This package is well worth the few pounds it cost. It seems well written and does the job its designed to do. Cant give it any higher praise than "excellent".
I did have a slight issue with the email cloaking plugin with j1.5 as it was intercepting the email addresses on the form but a fast response from their support team told me why and as I didnt need cloaking, switching off got everything working. It solves the task that we had of it which is all you can ask.
