Hi Carrie,

Yes, it's possible to create a page in Umbraco that only shows people who have already submitted a form using a specific identifier like an IP address or CRM ID or any Unique identifier (IP is some sort of personal data, so needs to be aware of GDPR or other privacy rules). Here's a high-level overview of how you can achieve this:

1. Identify the specific identifier that you want to use to track form submissions, such as IP address or CRM ID or any other unique identifier).
2. Set up a way to store this identifier when a user submits a form. This could be done using a custom database table, a cookie, or another form of local storage.
3. Create a new Umbraco page that will be displayed to users who have already submitted a form using the specified identifier. This page could contain a message informing the user that they've already submitted a form, or it could redirect them to another page.
4. Add some custom code to your form submission process that checks whether the user has already submitted a form using the specified identifier. If they have, redirect them to the new page you created in step 3. If they haven't, proceed with the form submission as normal and store the identifier.
5. If there are members on the website or any sort of logins using, then protect the page that has the form, so that way, only the login user can access the page and once the user logged-in then we will get the unique identifier such as Id, email or other unique identifiers, so we can check whether the logged-in user is already submitted or not !.
