Good free internet faxing?

[Ben E Lou]

Just did a search, and tons of stuff is out there. Can anyone help? Looking for something relatively simple to use, spyware free, and without overly-intrusive ads.

I use Efax to receive faxes. I have my own fax number and receive them as email attachments.

I think they charge you if you want to send faxes, so if that's what you're looking for it may not be what you need.
