Enable this to automatically activate new registrations in the CP

AutoActivatePlugin.php

<?php
namespace Craft;

class AutoActivatePlugin extends BasePlugin
{
	function getName()
	{
		return Craft::t('Auto activate from CP');
	}

	function getVersion()
	{
		return '1.0';
	}

	function getDeveloper()
	{
		return 'Bob Olde Hampsink';
	}

	function getDeveloperUrl()
	{
		return 'http://www.itmundi.nl';
	}
	
	function init() {
	
		if(craft()->request->isCPRequest()) {
		
			craft()->on('users.onSaveUser', function(Event $event) {
			
			    // Only react on event of new user
			    if($event->params['isNewUser']) {
			
    				// Activate user
    				craft()->users->activateUser($event->params['user']);
    				
    			}
							
			});
			
		}
		
	}
}

Could you get this to work for registrations from the front end instead of the CP?

Edit - looks like I just needed to change "isCPRequest" to "isSiteRequest"
