There is a website called
www.FaxCompare.com, and it compares all of the different kinds of internet fax services. There are some on there that are for larger corporations, and then there are others where you can simply pay a (very small) fee for each that you send/receive. Depending on which one you choose (according to your needs), your service provider will either offer customer service to help you learn how to use your service, or there will be step-by-step instructions and/or a demonstration on their website.
