The Add Member Column Wizard allows you to quickly and easily add common demographics columns to your members table.
Just check the demographic columns you'd like added, and click on
Note that you may change the Data Type. For the predefined fields, it's best to use the default settings (e.g., you would not want to use anything other than "date" for a birthday field). However, you may want to change the data type for the more generic fields, or make the address fields longer.
If you'd like to name your own column, use the Add Member Column utility.
