Hi, yes I have. I find it extremely handy. Only thing is that I think the charges from most companies seems to be quite high (or in my opinion anyway...) just when you consider how often you might actually use a fax. Ive used Blueface before - that was good as the fax service was thrown in free and was very reliable, never had any issues. The only problem was sending international faxes - I couldn't do that, but maybe it was the package I was on didn't support it. I've also tried i-flow.com in the past too. That was fine. Faxes were sent and received fine. Try the free trials and see how you get on.
