oh sorry, I should probably follow up to that Widener post...

I actually don't know very much, but it seems there was an anonymous threatening message written on a bathroom wall in one of the dorms.

Later that evening, they re-opened the campus with no explanation.

Glen thinks it was staged so they would have a reason to try out their new notification system where they email and text message everyone. My text message read:
SUBJ: EMERGENGY WARNING --- THREAT OF VIOLENCE
MSG: Report all suspicious individuals and activity to Campus Safety at 610-872-1392. Check email/web.

I'm not sure that was super helpful, since I would have to make it to a computer to find out I was supposed to stay where I was. But I guess it was a step in the right direction.
