Redirection URL for Newsletter

I have been trying to use this plug-in with 2 of my client's websites. However, I have encountered a few problems. One is how to redirect a new subscriber to a URL for a download link. I don't even see a Thank You email response capability.

Second is in using the template. When I click on Content in the editor is collapses the window and I can't see where to put information in. I've tried it on both Firefox and Internet Explorer.
