Update

Ok, so I spoke to my advisor this morning, he said he put in a call to the registrar yesterday to get a status, but had not gotten any response.

Then, this afternoon, I called the registrar directly, whereupon I was transferred to the surliest representative ever.  I barely got two words out of my mouth before she was jumping on me.  However, she did tell me that the registrar had gotten an email stating to post my degree that day, and that they did so.  So, supposedly, I have indeed graduated now.  However, diplomas don't get mailed until sometime in June, so I'm not taking anyone's word for it.  Until I actually have my diploma in hand, or a signed legal document stating that it is on its way, I'm not going to let my guard down.  Lawyers are still on standby, just in case.
