"For Monday, 2/2, I will be out of the office but checking email frequently. If your matter is urgent and/or timely, please indicate by using "URGENT" in the subject line. Thank you."
Reading this I wondered what you should put in the subject line if your matter is NOT urgent and/or timely. Right now I'm going with "Time Suck." Later on in the day I might change that to "Utterly Superfluous."
