Just putting in my two sense - this is going to be a mess of random history and trivia and opening up old wounds unless it's done correctly. To make an actual timeline, it'd be best for a person or small group to work on that, getting facts from the community, rather than simply making a thread where people will post anything in any order.
If people like exploring the old forum posts, this might be a perfect job for ya. I don't know much of what happened before NN got here, but I can certainly be of assistance with events within the past 6 months.
