I started testing it yesterday. If you install the entire system, it is essentially a WordPress plugin. The plugin adds the opt in form as a widget. The autoresponder part is installed in a separate directory. At this point it looks like the autoresponder scripts must be installed on the same domain as the opt in form.
My ISP went down most of the day yesterday, so I could not finish the testing. That might get done today.
There are some gray areas in the instructions. Andy, I will send you a list of recommendations when I finish the testing.
