Someone who sends out the announcements for a related department always does so by attaching an enormous color .pdf poster and sending it with the message. No subject line. No text. You
a. open the message every time, wait patiently for the .pdf to unfold itself, fight off the "Update me now!" messages that happen EVERY time you open Acrobat, and think "Isn't it nice to know about this event."
b. delete the messages without reading them.
