We just got a staff email from the IT department last week, demanding that we not use Doodle for setting up our "business appointments" because it is "insecure". They offered a link to a system programmed by IT persons who have never actually tried to make or change a multi-person appointment in their lives.
I checked the calendar - it was not April Fool's Day. I'm not really sure that my appointments for meetings and exams falls under the category of secrecy necessary in order to maintain national security. I emailed my departmental colleagues, and the non-TT-person came up with a splendid answer. "Business? Hell, I'm a slave here. I'll doodle if I damn well want to." Good. We'll just carry on as usual, ignoring the IT department. They don't help us, anyway.
