Does anyone know if any of those free phone number plans (like netzero) also have a "fax" that uses the email? :g_shrug: TIA

To just receive faxes, and if you don't care what area code is attached to the number they give you, Efax is free:

If you need to send faxes (plus get a toll-free number), then Comodo is much cheaper than Efax's "premium" offerings:
