I have a form to sign up to getting a rss feed through Feedburner.
this is the code - 

```
<form action="http://feedburner.google.com/fb/a/mailverify" method="post">
    <p><input name="email" type="text" /></p>
<input name="uri" type="hidden" value="dafyomi" /><input name="loc" type="hidden" value="en_US" /><input type="submit" value="click here to send" /></form>
<p> </p>

```

I want it to also sent the form data to a new window, and also change the window the user is on now - to a thank you page on the site.

Any ideas?
Thanks!
