Sure, I just added the CSS class pref-mailing-list-mode
.
@jesselperry adding this custom CSS will do the trick:
.user-preferences .pref-mailing-list-mode {
display: none;
}
To turn off mailing list mode for all the existing users, run this command in console:
./launcher enter app
rails c
UserOption.update_all(mailing_list_mode: false)
