I’ve been looking quite some time after a good easy to use free tool to get my few faxes sent online, now and then. In my willingness to serve the web community, here is my choice and best rating from far: Myfax.com. Beside a regular business offering, Myfax.com is also proposing free services, with no Ads and nothing hidden at all:
MyFax allows you to send up to two faxes per day, 10 pages each. Fax documents such as word, excel or PDF files anywhere within 41 countries.
This was exactly what I needed. You can learn more about MyFax/Free here (FAQ).
