Village tab in the kin window that lists people in your village. Other than having someone in your kin list or them being on screen there isn't a way to exile someone in your village who has been say, hacked, or turncoat or w/e and needs to be kicked.
Edit: Note, this si also a way for larger villagers to discover and meet new members without freaking out because they weren't informed.
Village noteboard of some kind @ the idol or such. YEs, I can make a basket and stash notes in it for villagers to read. but there is no way to know who has read your messages,or what 's new etc. without reading them all every time you log in. NOw I don't suggest that this shouldn't consume resources like any other mail system but it should be given an intuitive interface to manage distrobution of village instructions. It could also include tiers of privacy. Villagers only, target only, or fully publicly viewable. This would allow you to leave public announcements for visitors to read should you allow them (as say, brodgar does).
Intergovernment discussion board, possibly at RoB or like server chat. Eassentially this functions as a message board for lawspeakers and chieftens to make diplomatic announcements and public relations between important people about important matters that need not be public (Significantly less important and meaningful at the current stage of game development/population than the other two suggestions, and may be a forum board function).
I had a few more last night but I'm brain farting. So when i remember them I'll post/bump the thread.
