Appointments+ Login/Registration Behavior

Hi there!

2 questions:

1) How do I allow front end registration for Appointments? When I have "Login Required" selected it says "Please click here to register/login" on the front end, but there is no option to register. Under general settings I have "anyone can register" selected. What am I missing?

2) I'd like to allow people to login using Facebook or Wordpress, but I don't want to say "Login with Wordpress" as the general public does not know what that means. (Hard to believe, I know!) How can I change this?

Thanks!
