Invite_Sign Up Page

Anyone know how I can do the following:
1 - I want my invite_signup.tpl page to NOT show to header (as all pages do)
2 - If the above is not possible, is it possible to redirect the Invite_signup page to a different URL? Example -- after they click "signup" and enter the needed info -- they are currently directed to "invite_signup" page (where they can send friends referrals, etc. I need my users to see this page (witout the header) or, I need to to see something else altogether

To redirect to some other page, you can edit the template file and add javascript/html redirection code into it.

I edit the Invite_sigh up page with this code?
