This is more of a feature request then a question. I think it would be useful to be able to hide the form when the number of entries has been reached. It would be even better to be able to show only an HTML field after the form has reached its limit.
I am working on an email subscription form and it is only used once. I would like return visitors to the from to see an HTML formatted message thanking them for their response. Even better if we could use the name they submitted in the form so we could thank them personally.
