As for a bulletin board, here's my example of what it should be. I don't know if it's do-able, but it would be just one post that would be able to be edited instead of one that updates with additional posts. The difficult thing would be deciding who is in charge of recording the information and updating what goes on.
BULLETIN BOARDCURRENT LEADERS
Hokage: Kage Lennon
Kazekage: Sannin McCartney
Mizukage: Kage Harrison
Raikage: One And Only
Tsuchikage: Genin Ono
VILLAGE NEWS

Updated 5JAN15Suna: Experiencing record rainfall. Kazekage McCartney requesting local ninja to help with flood repair.
Updated 6JAN15Mizu: Currently under a tsunami warning. All hands prepare to protect the shore of village to prevent any damage from occurring.

Updated 6JAN15Tsuchi: Tsuchikage is throwing a party within the city to celebrate recent peace talks with Hokage Lennon. All are invited

And I guess here, people could request different things. Like people could PM the people in charge of the board and put out things like Genin Richards is looking for a team in order to accomplish something. It would kind of serve as those boards you see at supermarkets where people put up guitar lessons or babysitters.
Wonder if anyone else thinks this is a good idea/format.
