In the top right corner of any page, you should see the words: "Sign In."
Click Sign In and a sign in authentication should appear in a pop-up. You can sign in with your Facebook account or enter your email and password. When you're done click on the "Sign In" button and you'll be all set.
You can create an account by clicking "Create an Account" in the sign in pop-up box.
