One of the first things to do in the New Year is to change the copyright year at the base of your website.
My clients who have a website with create.net can do this for themselves by going to 'Site Content' in the top menu then 'Edit Site Information' in the side menu. Scroll down to the 'Page Footer' editing box where your copyright information is entered and change the year.
Remember to press 'Save Changes' at the base of the page when you have finished and republish your website - press 'Preview/Publish' in the top menu.
