Incorporate OAuth into the Login #12
Description
Right now, the passwords are hashed and stored using bcrypt. Because the site is accessible on through https, the passwords should therefore be secure. However, using OAuth would make it even more secure and the site even more appealing. Google OAuth seems like the easiest most logical option, but if you have experience with another API, that is an option too as long as it is secure and trusted (i.e. not Facebook).
