Is the WT prohibition of "bulletin board" based on the related Papal Bull?
I was told years ago that the word bulletin was related to the Papal Bull, and 'We are not in the Catholic Church, brothers!', so the word bulletin was out. Of course, silly, but that was the reason given that we did not call it a bulletin board. This, despite that fact, as Blondie noted, the early predecessor of the Kingdom Ministry was called the Bulletin.
