Useful code: Removing "Gimme a site! / Just a username please."

The option for a blog/user has been annoying me for a while because it's useless on my site. So I decided to find a way to remove it, and it turned out to be super simple. Now it just does blog by default. This goes great with Pro Sites!

function remove_signup_option(){
	global $active_signup;
	$active_signup = 'blog';
}
add_action('signup_hidden_fields','remove_signup_option');
