462264 Autoresponder setup

I have a website with a sign up box but cannot figure out how to insert the autoresponder code. I have tried to set up the campaign but am not doing it correctly. I use [login to view URL] for my autoresponder service. I want viewers of my website to be able to enter their email address and sign up to receive a free report. The autoresponder should capture their email address and send them the report. I also want the autoresponder setup to send subscribers a periodic newsletter. Thanks.
