One of the best form builder plugins. I tested/purchased many, but ultimately we choose ARForms as our standard formbuilder.

We use ARFORMS for visitor registration for events. What makes ARForm very good and unique is the ability to store the data in a MySQL database.

In addition, the support is very good and you get help quickly and issues are resolved.

What I would like to see added is the ability to assign a unique number to each record that is stored. This should include the ability to specify the length of the number, including the use of letters. Compare it to a password generator.

The second option would be to generate a QR code from this number that you can use in email or the ability to use a third-party plugin for this, for example.

I know this would require customization, but I think these would be good additions, partly because some of our competitors already offer this option.
