Who EVER fills out the yim/aim/jabber fields in their wordpress profile? not me and not clients lol... in this, it removes those three fields and adds twitter, facebook and google+ profile url fields. How to add those those new fields to the front end is included in comments

wp-user-custom-fields.php

// Add custom fields to user profiles
function vuurr_sm_contactmethods( $contactmethods ) {
        // Add
	$contactmethods['twitter'] = 'Twitter';
	$contactmethods['facebook'] = 'Facebook';
	$contactmethods['googleplus'] = 'Google+ About';
	// Remove
	unset($contactmethods['yim']);
	unset($contactmethods['aim']);
	unset($contactmethods['jabber']);	
	return $contactmethods;
}
add_filter('user_contactmethods','vuurr_sm_contactmethods',10,1);
