LOL! You can see from the response that people don't know how to follow instructions - "but I want to do it MY way!"
It said fax. So fax. It still a very vital and heavily used business tool. It didn't say E-mail. People rely too much on E-mail these days and it's making them very lazy showing that they don't know how to use business tools - like the telephone, mail, facsimile, etc.
I mean really how hard is it to walk to a fax machine (the copier and printer these days), type in the number and hit send? All contracts, RFP responses, bids, etc are either delivered to me, by my requests and by legal by hard copy or fax only. Final signing being hard copy mailed (well overnight with confirmation) AND faxed for records. Failure to do so indicates a basic failure of being able to follow directions.
