Order Statuses

Hi

I have two questions someone can help with.

I want to firstly:

– rename or add Order Statuses
and secondly.
– Stop emails sending when changing statuses

I have looked at a few links such as
https://www.jigoshop.com/documentation/turn-notification-emails-order-processed/
But it doesnt work.

Any help appreciated. Thanks,
