Love to see the FORM offer the option for the user to submit again after a successful submit.
In my case we use it for a newsletter sign up so entering multiple users would be helpful.
A simple option under the "success" tab would be to have the action reset the form for a new entry rather than just post a "you are subscribed..." message. The same way it does on the "error" message.
No doubt it's a simple fix and I'm just missing it....
