This may be a rather odd question, but a client would need to receive answers in a format that can be saved as a record. For example if the user were to fill in the form on paper there would be a hard copy of the questions and their answers. Would this be possible with FormCentral? Could this be received as an attachment in a notification?
I don't know if it is the best solution but you could filter the results to just that client's answers on the summary tab and then PDF that.
