It would be nice to have something like that (you know, like the message of the day in Guild) for one-liners. That way, you don’t have to go off the game, log in whatever website or forum the guild has, to just leave a question for members who might not be on when you are on and stuff like that. It could even be made as a Guild Hall upgrade – with care not to make it just for high level guilds but more like the guild bank first tier.
