By hand
In the admin
- In Settings › Audience, keep Let readers sign up and sign in on. With it off, no form shows.
- In Newsletters, turn on Subscribe newcomers automatically for the lists a form joins when the reader picks none.
- Use a theme that carries a form: Atlas puts one on its front page. For a form in another place, ask an admin's agent, as below.
- A reader types an address and presses the button. They get one email, and join your lists when they press Confirm subscription.
The form is part of the theme and wears its style. The confirm email and the confirm screen are PixelGlass's, in your theme's colours and fonts.
