I (and others) receive the following error message when submitting: "There was an error communicating with the server. Click the Back button in your browser and try resubmitting the form." I do that, but get the same results.
I'm very sorry that you're experiencing a problem with FormsCentral. This is a temporary intermittent server problem that we are aware of and we're working extremely hard to restore service ASAP. I will update this thread when it is resolved.
Today's server problem has been resolved. We apologize and thank you for your patience.
