if(!function_exists('remove_plain_bio')){
	function remove_bio_box($buffer){
		$buffer = str_replace('<h3>About Yourself</h3>','<h3>User Password</h3>',$buffer);
		$buffer = preg_replace('/<tr class=\"user-description-wrap\"[\s\S]*?<\/tr>/','',$buffer,1);
		return $buffer;
	}
	function user_profile_subject_start(){ ob_start('remove_bio_box'); }
	function user_profile_subject_end(){ ob_end_flush(); }
}
add_action('admin_head-profile.php','user_profile_subject_start');
add_action('admin_footer-profile.php','user_profile_subject_end');

Thanks for this. I'm inserting a custom WYSIWYG field to allow for links in the bio, so I needed this.

I'm guessing
if(!function_exists('remove_plain_bio')){
should be
if(!function_exists('remove_bio_box')){
?
