We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
You can set your form to disable after reaching the number of submissions.
To do this, you will need to edit your form and go to Preferences
Under General tab, go down to Status and select Disable on submission limit
A new field will appear and enter your maximum number of submissions before it gets disabled.
Lastly, click the save button and you're done.
