How can I change the ordering of menu items -- for example to make 'Wordfruit Copywriters' appear before 'How can you sell more of your product?' here: http://richardclunan.com/
Go to appearance -> menus section. Here you can create menus, add menu items and drag them around to place it to your desired place.
Alternatively, you can set up the menu order of a page. Just click edit page and you will see the menu order it should be under Page attribute section.
