You can now log in using your Twitter account. Support for other social networks will come shortly. To connect your existing CougarBoard account to your Twitter account, just log out, and then click the "Login with Twitter" link. After you accept the connection from Twitter, 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 Twitter, it'll just be a one-click login.
