Assistance in Web Form code editing

I need programming assistance in changing this web opt-in form: [login to view URL] Right now, when people sign up, text shows up below the form fields alerting them to check their email. INSTEAD, I would like the subscriber to be taken to a different page when signing up: [login to view URL] Additionally, the form shows a glitch in IE (a small white bar at the bottom of the sign up box) that I would like to fix. Thank you!
