If one of the fields in the form is used to define the user's association with one or more groups (the field name is "group" and the field values are the group numbers), then that piece of information is stored in terms of the user's belonging to the selected groups. For example, a question on the form could be: "Which sports do you like?" and the answer a series of checkboxes that correspond to groups you have created in your administration console. When users update the form, their association with the checked groups will be updated in the contacts database.
