PUBLISH “NAME” FROM FORM SUBMISSION

I would like to publish the name of each person who submits the Contact Form…which I am using to register people for an event.

Is there a way to do that only using CF7 or do I need an other plugin?

If possible, I’d like to publish the names in a list above the Contact Form so people can see who has registered. I’d be OK with publishing the names on a sidebar widget.
