What language is this?
What language is bg code for? I'm trying to make boxes to explain what each of the languages are, both in English for English speakers and in the language of the category of users, and I can't for the life of me figure out what this one is. If anyone would care to illuminate me it would be much appreciated! :-) Thanks, --Trinity507 23:03, 30 November 2009 (UTC)
