Ever wonder how to replace that cheesy ‘Howdy’ text that shows up in the WordPress admin? It’s actually rather easy to replace, and is one of the main things I do on every WordPress install now. Pop the following code into your function.php file in your theme, and change the text to something less.. lame.
/**REPLACE HOWDY**/
add_filter('admin_user_info_links','howdy_msg');
function howdy_msg($links) {
$greeting = 'Welcome Back';
$links['5'] = str_replace('Howdy',$greeting, $links['5']);
return $links;
}
/**END REPLACE HOWDY**/
