We can add lots of contact information, depending upon your needs. To extend user contact info, open the files and add in this code
<?php
function my_new_contactmethods( $contactmethods ) {
// Add Twitter
$contactmethods['twitter'] = 'Twitter';
//add Facebook
$contactmethods['facebook'] = 'Facebook';
return $contactmethods;
}
add_filter('user_contactmethods','my_new_contactmethods',10,1);
?>
This is only a basic example and you can make it more complicated depending on your creative needs
