Is there a way to modify the form so that a person can only submit once? (I've got a voting form and want to limit it to a once-per-person vote.) I know I've seen this on some polls where you are allowed to vote only once.
Thanks!

Using your MySQL db you can mark entries as unique. This forces duplicate entries to be ignored. So if you want to limit the entries per email address, mark the email db entry as unique. There are other methods you can use in the process.php file but the MySQL is the easiest to set up.
