Computer-mediated faxing is a simple as signing up with an online faxing service, whether you need incoming or outgoing service.
I use a fax-to-email system, efax.com. Incoming faxes are received as a digital file, which may be viewed, printed, and stored.
In the last year, I received 13 faxes, almost all were confirmation letters from the retreat facility that I rent for my monthly train-the-trainer class. All of my other business acquaintances have transitioned to e-mail. Gone are the days that I waited for the FedEx, UPS, and Mail carriers to bring me contracts and checks.
