how can I do something on new user registration?

Question

When I register a new user to my blog, I always receive an email. The code in simple terms should look like this.

on_new_user_registration(){

        //send email to admin
        //I want to do something else.

  }

I would like to do more than receiving an email. Can someone point me to the right code.

I have tried using the wp_insert_user() function in wordpress but that creates the user inside the editor.

thanks a lot.

You want to use the user_register hook, probably. Then use the Filesystem API to make the folder. Be aware that filesystem manipulation is dependent upon server configuration and may not always work, but using the API should ameliorate that problem as much as possible.
