By clicking the Columns button in the Guests tab, you can add more columns to your view.

In the Manage Columns window, you'll see two types of columns: Event Columns and Columns from Other Events. 

Event Columns includes your contacts' basic information like first name and email, as well as responses to your event's RSVP form.

In the Columns from Other Events section, you'll see all questions you've used on RSVP forms for other events. Pull in these columns to see a more comprehensive view of your guests' info and history.
