Thanks for the info. If only I had been more patient or just aware that I could not have purchased today anyway. I am confused as to why exactly there would be different variations of "Certified mail" that could effect your temporary paperwork. I guess my only question is why I would be able to choose certified mail from a list of options, pay for it and get a receipt but that the receipt isn't sufficient proof of mailing. Is the type of certified mail where the postal employee stamps the green receipt a different certified mail service? I'd be surprised if this is the first time this has happened to someone
