title: WooCommerce require registration to buy
body: <p>I need to require a user registration before buying a product. Right now, when you add a product to the cart, then in the check out you can fill all the fields with your information but without a wordpress login. There is a simple option to create an account but is optional. </p>
  
  <p>I'd like to know if is possible to modify the check out page to redirect a register page. </p>
  
  <p>is it possible? </p>
  
  <p>So if you wish to give any suggestion or any interesting link that will also be highly appreciable.</p>
