Yes-we love our filters!
To filter within your Guest List use the Filter Guests dropdown menu to filter by "Definitely Invited," "Maybe Invited," "Missing Information," or "Relationship to You."
Within the Track RSVPs tab, you can also filter by guests who are "Attending", "Declined," or have not yet RSVP'd.
