sending a fax via email?

[Carameli]

has anyone sent one before and which company did you use???

Nope, not done this, but if you have Windows have a look in your Programmes-Accessories menu (or the equivalent if your version of Windows is more up-to-date than ours) and you may find a fax utility. I've used ours many times and it works fine. I don't know how to receive a fax with it, though.
