The supporter_volunteer object contains volunteer information about supporters. The table maps a one-to-one relationship with a supporter. That is, a supporter can have one, and only one, supporter_volunteer object.
The only supporter_volunteer field currently populated by by Salsa HQ is the "Availability" field. Availability fields are provided to supporters in signup pages that have the "For volunteers, request availability" checkbox clicked
This is a sample signup page that requests availability.
Here is the layout of the supporter_volunteer table.
