New User Notification

I am creating a web site where the users have to be registere in order to access the site. To accomidate that i have created a registration page.

But registration alone will gurantee automatic access to the site, therefore the default access level is set at guest.

So far there is not problem.

Now the feature i am looking for is to get notified by the server whenever a new user has registered. That way i can review the infomration and then adjust the access level accordingly. Otherwise i have to check the database everyday to see if anyone has registered!

Anyone knows a good way to get this accomplished.
