Good news: Our weekend project of building a time machine seems to have worked!
Bad news: A bunch of our email got sucked into the time vortex, so email messages that we received between January 23-25 are being received again. I guess we shouldn't have hooked the flux capacitor up to a computer that has our email account on it.
Actually, we have no idea why some (many?) staff are receiving messages again that were originally sent between January 23-25. We are investigating it, but so far cannot tell what is causing it. We will continue investigating and post updates when we discover something useful. Sorry for all the confusion.
