If we made one big card, we could send one big "Happy Birthday." Underneath we could each give our own personal message. If a number of people want to say something, as individuals, about, say, choreographers, she'll get the message, I hope. But the overall message should probably be a simple statement of admiration and support. Imagine how you would feel if you got a birthday card that read, "Best wishes from all of us, but some of us think you should change your life, associate with different people, lose weight...," and so on. You'd probably have mixed feelings. I think you get my idea.
