Send a fax directly from your web browser, multiple browsers are supported. The simple setup of the page allows you to register and send a fax all from the same place.
The free fax is limited to 5 fax's a day. However, along side the free fax service they also provide an "almost free fax" service. Both are on the same page, this contributes to the ease of use for the site. The almost free fax service costs $1.99 but allows the sender 15 pages and a priority delivery over the free users.
