First off let me start by saying, great add on, this really saved me when another form I was using stopped working and I had to start from scratch.

I too am trying to add some Adwords Conversion code to track how many people actually sign up to the list through this form, coming from our ads etc.

Which files exactly would I need to look in to do what you are suggesting above, I have gne through many files within the modules, components and libraries asociated with CMC but as of yet am not having any luck with where to add this Javascript code to make it only display if the form is submitted with a successful email added to the list etc.

Thanks in advance for any assistance.

Hey Mike,
You could modify the js file that does the ajax subscribe. In the funciton that deals with the request from the server you could add your googleAnalytics code and this way you won't have to do a redirect.
