There used to be a time when there was no bn in Mozilla. There was only bn-BD. Now, there is bn, bn-BD, bn-IN. * We only have bn in Transifex and most translators say 'it is almost the same'. * We haven't got an alpha now because of legacy/trac#29257 but it will be called bn-BD * The translators are quite active and our documentation is already translated, they are translating only one language as bn in Transifex. This ticket is here to take a decision about that.
