Please review my app:  RightSignature.com - Easy Online Document Signing
dmix: One detail I think is important: When I create an account I'd like to add my password at the beginning. I knew it would email me after requesting that I enter a password, but the mainstream user definitely won't.Security is a very important factor with your application and it helps to create that image even if it sacrifices some easy sign-ups.I often see many business applications that list "Secure Log In/Authentication" on the feature list as well because its not always assumed.
