Check user for previous submission

[ImagineWebsites]

Hello, can anyone tell me if there is a way to add something to a form, or an automatic check which can be set up to prevent a user from submitting the form more than once?

Thanks

I am using Form Tools 2.2.5

Yes, there is. Look at this documentation:

Thanks for pointing that out, I'd searched the documentation but guess I must have used the wrong search terms!
