Can I limit my form to a number of submissions?

Sure you can. It is really easy to limit your form to a number of submissions.
Following are steps to make your form expire once it reaches its quota limit:

1-	Sign in to your FormTitan account.
2-	Enter your form in the form builder.
3-	Open your "Form Properties" > "Settings" > "Limits" Category > Quota limit.
4-	Turn on the "Quota limit" checkbox and enter a number of max submissions. Once your form reaches this quota it will become inactive.
