Let me know when Google+ actually works with my google apps email address. It says you have to enable it but I did enable it (terrible documentation/help to do so) and still could never get it to work with no useful error about what's wrong. It should just work by default. And if it's disabled, they should stop sending me emails asking me to sign up when they know perfectly well that they won't let me.
