Hello Steve!
Yes, our Contact Form plugin allows you to register users, who submitted their data. Notice, that this is PRO option. To enable it, go to your Contact Form edit menu https://prnt.sc/fdsfny. Then open Submit Options tab (1) and Registration subtab (2) https://prnt.sc/fdsgfx. You will see the “Enable Registration from Form” option, select it. Now you can set the role of registered user and tick Ignore confirmation option https://prnt.sc/fdsk6l. Check more information here https://supsystic.com/documentation/contact-form-registration/
