It would be useful I think, but not as a free-for-all option... it should be more limited. i.e. for rulers, for dukes (to send to their duchy), for lords (to send to knights) etc.
Then again, the Report tag pretty much does the job right now IMO..
I think that the current system where everybody can send Orders is much better than the old one where that was reserved for Marshals. I think the same system should apply to Announcements. I have no fear that an adventurer sending an announcement would be met with the same ridicule as if he were sending orders.
