[support] Email notification on new user registration

[Nikhil Kala]

Hello,

I want send email notification to site administrator, when a new user 
registers on the Drupal site.
Is action and triggers are sufficient or I need to use Rules module?

Secondly how I can send the username of the new registered user and site 
name in the email?
I have tried *!username *and* %username *but it is not showing username 
of the newly registered user.

Can any one through some light on this....

Thanks,
