When my e-mail account at LSE was turned on, the first e-mail I received was from the sys admin. It read: "Please ignore this e-mail. This is just a test."
Of course, if I ignored the e-mail, I would have been doing what it said to do, which meant I wasn't ignoring it. So should I respond? I finally decided it was an initiation rite for new philosophy students -- anyone who was so freaked out by the conundrum that they didn't show up in London wouldn't be able to cut it in philsophy classes.
