I liked the clear simple explanations.and the fact that it stops you from clicking on anything until it has explained the basic functions of the key attributes. For some of us who think they can probably figure it out on our own the little speed bump and wake up call save a LOT of time.

Really easy to use The web interface is really easy to use. The "wow" feature for me is that you can setup a default signature and copy and paste it on documents as you need. This has saved me from losing time with some legal documents I need to sign while I'm away.
