Have you considered doing the translations using Narro?.

Narro is rather off-topic here, as for most Indic languages due to how
those teams work technically.
Also, I've seen *her* on irc in the past few days.
If you're having concrete problems with the bn-IN localization, please
file bugs at
https://bugzilla.mozilla.org/enter_bug.cgi?product=Mozilla%20Localizations&component=bn-IN%20%2F%20Bengali%20(India),
you should probably read
https://developer.mozilla.org/en/Bug_writing_guidelines before that.
In general, open source communities don't respond in a matter of days,
so you don't want to put too much weight on that.
