New user registration with email notification to admin

Hi.

I'm trying to create a project that allows people to register into one of my database tables. That's all the project does. I currently have it set for No Login on the Security tab and the landing page is the "add" form.

I want to have it send me an email when people complete the add form. I see that I can do that in Registration and Passwords. However, when I open Registration and Passwords, everything is grayed out.

If I change to hardcode or database log in, the Registration and Passwords is not grayed out. However, with that setting when users go to the url for the add page, they are redirected to log in.

Is there any way that I can have people who are not registered go directly to the add page without having to sign in AND set it up so that I get an email?

Thanks.
