Definitely the discussion board. It's very, very hard to get news across to the guild.
I'd also like some sort of news system where those with privileges can post news, and some sort of icon that blinks when there is new news. Either that, or have it so anytime there is a new stickied post in the discussion board, there is some sort of blinking icon so the player knows there is news to be read.
