11-2-2021 Facebook Login not Working
If you use your Facebook credentials to log in (or if you know of friends trying to sign up using the same), please be aware this is not working at the moment. If you don't already have a "regular" sign-in (Username/Password) you can set this up by using the "Forgot Password" function on the site.
We are working on restoring the functionality, but since it depends on Facebook as well we cannot give an estimate of when this may happen.
