[Plugin: Contact Form 7] "Thank You" page

I installed Contact Form 7, and everything works great. However, after the “submit” button is clicked, I’d like a “Thank You” page to load.

Currently it loads a page that says “There is nothing here”. (probably a blank “filler” page added by the creator of my template).

What can I do so that it shows a Thank You page?
