Only registred users are authorized to subscribe to my newsletter.
So, I don't want double optin and in configuration panel, I put "Confirmation requise (double opt-in) (required confirmation)" on No.
When an user suscribes to the newsletter via the acymodule, a mail with a link is send to him !
What is curious, it's the mail is send only where user's email is showed, not when there is only name or html (module configuration "Champs affichés (displayed fields)").
An other thing, in module configuration, it's not possible to have "Champs affichés (displayed fields)" empty, what I want.
Thanks for your response
