I have a landing page that pops up 10 sec after someone visits my website. It's a simple page that has an image in it. I want to replace the image with subscribe form that will unlock a coupon code after the subscription. When a person enter his email and press subscribe I need it to stay on the same landing page with the image of the coupon code and a Thank you message and not closing that landing page automatically - need the person to close it as soon as e finish reading. Any Ideas?
