It would be nice to hook together the built in vBulletin language system with vBET. This way there is more control over the phrase translations, some things don't have to be run through Google to be translated, and more human translations will exist and be more accurate.
So for example, if a user selects the Spanish language, all posts and other text are run through vBET and all other phrases, if they exist, are handled by the Spanish vBulletin language pack.
