Another method that can be used to populate your list/committee roster is to specify the list you would like new members added to within the membership type setup. See Automatically Adding New Members to a List in Action!!
One of the parameters you can configure for your membership types is Add to List. By defining the list to which you wish your members to be assigned, each time a membership is activated, whether by completing the online application or by adding a membership from the back-office, the new member will be added to the selected list.
