Hi Lucy Leu, thanks for the question. The "I Did This" works the same as it did before, although we did change the button language from "Save" to "Send." Your comments are associated with your I Did This, which you can access either from the video page or from your profile. Just to be clear, your comments are visible by other Grokkers. People typically use those comments to describe how they felt about that video, which is useful for other people considering it as well.
