The disappearing job ad...

I found this job last week at the University of Chicago that sounded really good and here I am ready to write my cover letter and apply for it and I can't find it anywhere. Nowhere. I have the job description, which I copy and paste into an email and then move into my "Job Opps" folder. However, there is no contact information provided and it says to go to the U of Chicago HR page to apply. Yet, on the HR page, there is no such job listed. I have the requisition number - and nothing comes up. I don't know. It's like it vanished into thin air. I suppose it's possible that I missed the deadline or something and the job has already been removed; however, it was only posted ten days ago and, according to the description, the position was supposed to stay posted until May 2007 (presumably for six months). So weird. And kind of a bummer.
