            <h3>Customise this Theme</h3>

            Want to customise this theme? Don't edit the stylesheets or PHP files
            of this theme using the Theme Editor. Why not? Because when you use
            the WP upgrade mechanism to upgrade this theme, it blows away all your
            changes. The/One right way to customise themes is to create a 'child
            theme' -- that will be a feature available in an upcoming release of
            this theme. In the meantime, if you want to do the manual work, please
            <a href='http://ahren.org/code/contact'>contact me</a> for
            instructions.
