Page Forwards with AutoFill?

Is there a way to do forward a page to where a field on the next page is autofilled? What I'm trying to do is set up a link that will hit a page on my server, that will forward to an affiliate page. The problem is, instead of using cookies, codes or anything else from this century, they make people manually enter in the email addy of the person who referred them. This is a genuinely awesome webjob that I think a lot of people need to see (aside from being completely free, easy and fun). I'm not pitching it, but I want to, and I can't think of a way to have that email field autofilled for them. Any suggestions?

where are you getting the e-mail from ?

::edit::

Can you do it with a hidden form tag ?

View the source of the target page with the form.. Find the name of the text field that you want to fill out.. Try to pass it in the GET request.. IE: site.com/page.html?field=text

It may work depending on how the form is written.. I know it works on a lot of php forms that pass fields between get requests because most of them just call $_GET['fieldname']; .. You may get lucky.

You could also try hosting the form yourself and modifying the form action to post directly to their server.. This way you can pass your email address as a hidden field with the same name as the original form.. If they don't use cookies and shit from 'this century' then I doubt they do any referer checking on the form.
