Over 80% of what we send and receive by fax is "legal size" (8 1/2 x 14). Yes, I work for a law firm :) We had tried another Internet fax service a while back, but even though it would allow us to receive a legal-sized fax, it would always shrink it to fit on an 8 1/2 x 11 "letter" page. Sending legal documents as email attachments had the same effect (the receiver would get our legal-sized fax, but it would be shrunk to letter-size on the way. It goes without saying that this wasn't acceptable to us and so we've continued to use our trusty Canon laser fax instead. I'd love to have the on-line archiving and some of the other features I've read about on your site, but the bottom line is that we have to be able to send and receive legal-size faxes.
