It sounds like several of you know more than I do about this, so I'm curious... I'm in the habit of using Priority Mail for things like this, because I can print out a mailing label at home and get a tracking number with delivery information.
Assuming I put the tracking number in the letter as you suggest, is there still an advantage to using certified mail and a green return receipt instead? Or is Priority Mail equally good?
