 *
 * Allows the creation (and processing) of both "update" and "create" feeds on the same form with the Gravity Forms User Registration add-on.
 * Requires feeds to be configured with conditional logic based on a User Logged In field on the form.
 *
 * USE WITH CAUTION! If you are not handling which feed should be used via custom code or conditional logic, you will receive errors.
