WordPress MU

I am new to WPMU so forgive a n00b question.

I have figured out how to run my function when creating a blog:

add_action( 'wpmu_new_blog', 'my_function', 10, 2 );
function my_function($blog_id, $user_id) {
     // do cool stuff when a blog is created
}

I have this in a plugin file in my mu-plugins folder, and it works properly.

How do I hook to run when a blog is deleted?

I tried this:

add_action( 'wpmu_delete_blog', 'my_function2', 10, 2 );
function my_function2($blog_id) {
     mail(myself, 'hi', $blog_id.' was just deleted!');
}

But it didn't work. =(

Please advise.

Thank in advance!

Is there anybody out there?

<?php
add_action( 'delete_blog', 'my_function2', 10, 2 );
function my_function2($blog_id) {
//	$email = 'yourname@mail.tld';
	$email =  stripslashes( get_site_option('admin_email') );
	$subject = $blog_id.' was just deleted!';
	$message = $blog_id.' was just deleted!';
     mail($email, $subject , $message);
}
?>

Thank you so much!
