OK, this is a pretty specific idea, but I think it could be good. We've got bulletin boards for posting Notes in a few public places. Specifically lobbies of apartment buildings and community machine rooms. I was thinking that it would be nice to add a bulletin board to Uncle Friendly's Emporium in IX since there aren't any apartment buildings or machine rooms in Ix, and alot of people spend a TON of time there.
Anyway, just an idea.
