Wooden signs and runestones are cool, but they only hold 100 characters each, limiting their usefulness. What if we could build a board that held only units of parchment, so people could post more in-depth messages to each other? These could be built outside villages or homesteads for communication with visitors or passers-by, or within a village or kingdom as a way to communicate with fellow villagers and whatnot. You could post bounties, MOTDs, recipes, or just chat with your friends. I figure it could hold a 4x4 or 5x5 grid of parchment. What do y'all think?
edit: just saw the thread jorb replied to and apparently this is suggested constantly, so I guess that answers that
