how to remove the "apply coupon" slide. Or redirect new members straight to a page.

I set up member ship on my page, but I'm not planning on charging anyone for it. When new users sign up, the last page they go to is a page that asks them to input any coupon code that they might have. I want to remove that page and send new users that just signed up, to one of my pages.
