I'm looking for a service where I can get a phone number that will
receive faxes for me and then send me the fax via email.  I'm
wondering if any of you use such a service with which you are happy.

I've done some looking and it looks like my best bet is j2.com
(formerly jfax.com).  efax.com would also be an option, but it sends
the faxes in a proprietary format and they only have readers for
Windows and MacOS.  j2.com can send them in TIFF format, so I could
read them under Linux.  (Now the message is more on-topic.)

Are there any others that I've missed?  Or does anyone have a word of
caution about j2.com?

TIA,

Eric
