This plugin is perfect because is very simple compared to Subscribe2 for example. But I miss two important features that would be simple to implement:
1) Customize email text (I need text in Spanish)
2) Configure category or categories for which the users get emails when published (putting a filter using function wp_get_post_categories inside ny_subscribe_notify_post function would be enough)
3) (More dificult) Support for qTranslate plugin
Thanks for developing this amazing plugin!!!
