A small PHP function by the way which allows you to remove the small WordPress logo from the administration bar, and therefore save a little space at the top of a WordPress blog on the administrator side:
// Remove WP logo and WP dropdown menu from top admin bar
function admin_bar_remove_logo() {
global $wp_admin_bar;
$wp_admin_bar->remove_menu('wp-logo');
}
add_action( 'wp_before_admin_bar_render', 'admin_bar_remove_logo', 0 );
To add in your functions.php file or via a WP Code type extension.
