I think, as our first official act, we should organize a prayer service or at least a candlelight vigil or something for the victims of the attack.
ETA: I've asked the Dean for candles so we'll see what she says and I will make a post about the vigil. Maybe tonight at 9 in the quad? If we don't get candles, I say we raid our rooms. I know Katja has a bunch of candles. I also like Nawal's suggestion of a moment of silence.
