A long time ago I had suggested that a wealth of events concerning specific regions be recorded. Kind of like a Character History for regions. Logging things like realm changes, lord changes, major battles, revolutions, region description changes and all that. I always felt that this kind of history would be an awesome RP resource. It would also be cool if the history of each region was accessible via API so that adding a running history to the wiki would be easy (exclude the last x days or something). I know I would have loved to have such information available quite often.
