You can now log in using your Facebook account. Support for other social networks will come shortly. To connect your existing CougarBoard account to your Facebook account, just log out, and then click the "Login with Facebook" link. After you accept the connection from Facebook, it will ask you if you want to sign up or log in. Just log in with your existing CougarBoard account at that point. After that, when you log in with Facebook, it'll just be a one-click login.
