Okay Brandon, here's issue #1: Every single old thread is posted as an archive, which means that authors can no longer edit existing posts. For those of us with say, stickied help or guide threads that we've been maintaining, this means that every single one of those threads will have to be re-posted and re-stickied so that thread authors can continue to update their posts.
This times a million. Unless we get editing back in a reasonable amount of time we'll simply have to re post any thread we've posted before.
Yep, my mail is gone as well. Checked in game just to make sure and it's gone there too. I use my mail as storage for BOffs and DOffs, just glad I cleaned it out for the most part yesterday. Only lost a handful of each.
