Hi, As we have done Bengali (bn) localization offline, please don't pull old translations from the Pootle server.
I have already put the SDF file online and put the link in the issuezilla [0]. FYI, UI and Helpcontent is fully localized into Bengali, except "migrationanalysis" module. Cheers, -Jamil [0] http://www.openoffice.org/issues/show_bug.cgi?id=106456
