too true. especially since grad students, by and large, change addresses often, live in temporary lodgings, share places with people they don't know well, or spend their summers travelling and doing fieldwork!! i remember doing my MA and checking a friend's mailbox for weeks after she had moved home because she was waiting for important documents to arrive. i don't trust surface mail at all, and it does seem like a colossal waste of money and paper (close to 8000 envelopes!). if not email, then why not just set up a secure site like OGS to check results?
all this waiting has turned me into an expert complainer.
