Event hosts can be sure that each person they put on the list will only correspond to one actual entry. Making events is simple with DoorList, as you can add users individually or add an entire organization. Further, you can allocate entries to others so that they can add their date or friends themselves. Event guests or organization members don't even need to be on DoorList yet-- you can add them by phone number so that all of their events and organizations will be there when they make an account. You can even repeat past events by duplicating the entire list!
