I have two guests who must be seated together. How do I make sure this happens?

Go to Guest List. Find both guests using the search bar and select their checkboxes on the left of their row. Then click the  paperclip icon in the header bar. This will link the two guests in Seatrobot for that event. When seating your guests, Seatrobot will keep them together. They will also appear together when searching for either guest in Check-In.
