Hi,
In the HikaShop backend, you have a sub menu named "Order Statuses" under "System".
Thanks to this view, you can add and modify your order statuses.
Do not forget to update your HikaShop configuration (System > Configuration > Main) for your statuses ("default order status" and others).

By the way, do not send me private message, use the "contact us" form instead.
