I don't know about the signing part - I believe it was signed (I will check after lunch when my coworkers are back). I had it shipped to my office so I can sign for it. But surprisingly it came in while I was out getting lunch.
And yes, there is a tracking number (on a USPS label) but its basically useless because the status still shown being sorted by the USPS.
#1 did you have to sign for it?
#2 was there a tracking # on the package?
