When I had a dial up connection and XP it was really easy. I think it took less than 5 minutes to send the first one. At the time I had to fax a bunch of things from the computer and they never got put on paper on my end. After the first one they were probably easier than using a fax machine.
Without the phone line now I was looking at it awhile ago and you could do it online but it was a bit more complicated. 3 pages max for the free offer. I don't have a scanner, couldn't get the document on the computer, so went down to the neighborhood print shop and faxed from there.
