Creating a tuning group
When you create your first tuning group all existing customers will automatically be assigned to this first group. Additionally the first group is marked as the default so that any new customers that register automatically get assigned to this group.
Discounts
You can configure discounts for tuning types. The discount is configured as a percentage off the normal price. These discounts are in effect when "Discounts enabled" is set to yes for a tuning group.
Deleting a tuning group
The default tuning group can not be deleted. When a tuning group is deleted that is not the default all customers belonging to that group will be moved to the default group instead. All credit amounts configured for tuning types and options for the group are also deleted with the group.
