New Staff <- Not getting an email with username\password

[Norsak]

I hope this is an easy question with an easy answer.

When I create a new User, they get an email telling them:
You have an account on support.blahblah.com
Your username is ..........
Your password is ..........

When I create a new Staff, they do not get a similar email.

I want Staff to automatically get an email when I create their account, and when I change their password.

Where would I configure this?
