Also their signup form inexplicably won't let me sign up, and doesn't tell me what it doesn't like about the form submission. This does not seem like discipline. Doesn't work in two different browsers. Anyone have a recommendation for alternative tools that do the same thing, but that aren't quite so customer unfriendly?
