Is there a limit to how many people can use the simple registration form for an event?

By default, there's no limitation in the number of registrants on your form. However, please take note that for the Free plan, you only have 100 submissions per month.

You can set up a form limits wherein the form will close once it reaches the number of registrations allowed. Here's how:

1. Click the "Preferences" button in the top toolbar.

2. Select "Disabled on submissions limit" in the "Status" and then set a number value in the "Submission Limit" field.

3. Click the "Save Changes" button when you're done.
