We just had to send a short fax, but, we don’t have a fax machine or even a fax modem. Faced with hunting down a fax modem, I did some searching and found FaxZero.com. This is a nifty service that lets you, for free, send two faxes of up to three pages per day (per email address, presumably). They add a cover letter that, along with sender and receiver contact information, has an ad on it, but, the ad isn’t too obnoxious and seems reasonable for the convenience. You can send a .DOC or .PDF files. One file per transmission. Neat stuff.
