There are non translatable strings in templates for example in delete_account.html: https://github.com/pinax/pinax-theme-bootstrap/blob/master/pinax_theme_bootstrap/templates/account/delete.html
It would be great if all strings were translatable.
Of course, the problem is that running makemessages in django-user-accounts won't help since the templates are in pinax-theme-bootstrap. So I'm also wondering what's your take on this.
Sorry to only respond now (2+ years later) but they are marked for translation now.
