Hi,I have a multilingual site that I translate with WPML and I have come upon a problem where the title of the widget of Subscribe2 did not translate. I have contacted people at WPML (Please see http://wpml.org/forums/topic/widget-title-not-translating-2/#post-89029) and they mentionned that it seems to be an incompatibility between their plugin and yours and asked if you would like to participate in their Go-Global program (http://wpml.org/documentation/theme-compatibility/go-global-program/) where they would help to make both plugins compatible.
You can see the problem at http://imgur.com/tasXn (the site is in development)
P.S. I managed to get the title translated with suggestions by WPML, by changing the code in widget.php to:
$title = apply_filters( 'widget_title', empty($instance['title']) ? __('Subscribe2', 'subscribe2') : $instance['title'], $instance ); But that is as far as I could go, not being very good at code and I don't know if it requires more...
Thanks and by the way great plug-in!
