How did you know a new feature was wanted if it hadn't been requested in the forum?
You have to trust your intuition. 
Anyway in recent versions, most of the new features come from user requests posted in the forum or in SourceForge tracker.
Were these emails sent to relevant translators?
Yes, to the contributors who proposed their help to translate in their language, and to the other ones who gently answered to help wanted posts when a contributor couldn't help anymore.I'm working on it now but might take some time since I need to attend several classes.
