Agree with all the positive reviews.
Updox is easy, not terribly expensive -- cheaper than paper and toner and fax machine repair/replacement -- and the mountains of paper have vanished.
Got to get some karma points just for not creating all that carbon footprint? (Of course, as my virulently non-tech wife points out, the data centers that run these things make their own carbon footprint-- no way to quantitate that
.)
