I hate hate hate sites that don’t update there copyright. I know if you don’t use some sort of template system it can be hard to shift through all of your pages to do this. So make your website with WordPress or hire someone to do it for you, I am busy I can’t help you.
Anyways in your footer now you should change it to:
Copyright© 1989 – <?php print date(“Y”); ?>. All Rights Reserved.<br/>
Copyright© 1989 – <?php print date(“Y”); ?>. All Rights Reserved.
So now with php the year gets generated dynamically, every year, So you don’t have to worry about it ever again.
