Hi, You have two options. One when you register the surprise, after the id, you have a text area "Feedback for your partner". This feedback is private and only you and your partner can see it.
The other option is to comment on the surprise's page. If you click on the id of a surprise, you will find at the bottom of the page a section for comments. This comments are public for everyone to see. You have to be logged in to be able to add comments.
