PM after a new member's registration

I have enabled activation by admin when a new member registers in my forum. I know that there is an available function which sends an e mail after every new registration, but i am looking for a similar one concerning private messages. Is there anything like that ?

Hello
u have to go to
AP>General> Messages and Emails>Privet Messages
then right the pm then press save

Nah i am not talking about the welcome message. There is an option that sends the admin an email when a new user registers. I want to know if that can be done with pm in the forum.

Hello,
Admin Panel=>USers&Groups=>Users=>Users options=>New accounts activation=>User=>Register.
Regards!
