It is easier to add new people (New Person records that are not related to EXISTING family records) using the "Add new Family" menu item From the People / Families Menu. Keep in mind that in order to start tracking giving or an address a family record will have to be created (which can be done from either the Add new Family or Add new Person menu item). See Family versus People Records.

6. Clicking "SAVE" will goto the family viewer, clicking "Save and ADD" will goto a blank family editor screen.
