My b2evolution Version: 3.3.3

Does anyone know of a jQuery script that would enable me to embed another website in my site. Something like using prettyPhoto or Shadowbox but instead of clicking on a link and pulling open the box, it would just remain an open frame within my site... optimally scrollable...

For example, I want to be able to put the contents from here: http://campaign.r20.constantcontact.com/render?llr=npklvidab&v=001qwhULkbmHDsuZd4HFeRcIJxVQ-pgnllAJf4vdhO59fYsMZUsEVzwuCCBV1sJJN53MK2Q8Xqlepgbgx0EhoBvWWhfLrVwqKUbVb7zon4qWm8KTevX3GN3Lv3ej3y1E9Fj

on my page here: http://wccoa.org/index.php/Home/newsletter/

Am I going about this wrong? Is there an easier way to drop a frame into my site that displays the content of another site?

Notice if you click on the HERE on that 2nd page, it opens the first page in a shadowbox style window - I just want that content on my page to start with...

Am I going about this wrong? Is there an easier way to drop a frame into my site that displays content from another site? Can I do this with frames?
