E-mail notifications of new strings available for translation

Hello,

It would be welcome if translators could subscribe to notifications of new strings to be localized in a certain file from their translate-dashboard.

(for instance with a simple checkbox available on each line of any file list: e.g. here http://translate.userecho.com/lang/en/ )

This way, they could react as soon as possible when new strings are added to the base language and that needs to be translated...
