Neighborhood Private Messaging, Please!

As a leader of a neighborhood, I would like the ability for us to send private messages within our neighborhood. I would like this for several reasons, 1)Privately reprimand those who've broken a rule without realizing it, and 2) Send messages to see who will respond, i.e who's active and who's not.
Private messaging, of course, can be for all members.

I have some members who may not chat often but help out others when they can. I would like an easier way to tell who's not doing anything or who's just wanting boat help without helping others.

Maybe also add a "last online status"?

Also, could we have some way of sending messages to those not in our neighborhood? Like a wall or something (similar to FB). The option to post a message would be available when you tap on the person's NH house to view their stats. The wall could be public or private with a limit on how many messages it can display. The user would be able to delete or keep any messages they wanted. If any of you have played a TeamLava or Storm8 game on iOS, you would know what I was talking about. :)

Thanks for reading and I hope something can be done in the near future!

Any additional ideas or constructive comments welcomed. :)
