Link profiler with author

Ok nevermind, I just resolved this by adding this code to profiler.php

if ($_GET["author"] || substr_count($_SERVER["REQUEST_URI"], "author")){
	add_action('wp', 'pf_redirect');
}

 	function pf_redirect(){
		global $wpdb;

 		if ($_GET["author"]){
 			$user_name = $wpdb->get_var($wpdb->prepare("select user_login from " . $wpdb->prefix . "users where ID = %d limit 1", $_GET["author"]));
        }
        else if (substr_count($_SERVER["REQUEST_URI"], "author")){
        	if (substr($_SERVER["REQUEST_URI"], -1, 1) == "/"){
        		$uri = substr($_SERVER["REQUEST_URI"], 0, -1);
            }
            else {
            	$uri = $_SERVER["REQUEST_URI"];
            }
            $pos = strrpos($uri, "/");
        	$user_name = substr($uri, $pos + 1);
        }

 		$url = "/users?user=$user_name";
 		header("Location: $url");
 		exit();
 	}
