At present, one does a selection of the people in NB and then clicks "export" and every single column in the database is dumped for each person in the selection. My suggestion would be to allow users to choose which columns they want exported to make it easier to manage the exported data. e.g. First_Name, Surname, Home_address or Work_address; this will make it much easier to do a mailout based on data exported from NationBuilder.
