I just read about the target attribute. It sounds like the simple way to use it would require submitting the form from a page already containing a frameset. I want a frame to appear only when the form is submitted.

Now that I think of it, I do have content in the center of my page that I can put in a seperate frame which could be the target, but scrolling would be necessary when once the form is submitted and a scrollbar in the center of the page would look horrible when my regular page content is displayed.

My original idea still seems necessary. I'd have the scroll bar only when the form is submitted, and a link back to my frameless homepage. If I do it this way, I'd coax people to press an extra submit button after a message stating that the following content is from another website, I'm not responsible... blah blah blah... click the link to return... blah blah... and click here (submit) to continue.
