Hell, I just know it's called "BBC." I don't know what it stands for but thanks. I edited my post with what I put in.

Edit: Flaw told me. Anyway, it's like BBC is trying to parse URLs the wrong way... weird...

The first thing that came to mind from the title was the British Broadcasting Corporation.
But then that made no sense, so I realized you mean Bulletin Board Code.
