How to use a form to enter information for an existing user OR new user

[Meg_Green]

Hi all, I'm creating a form for volunteers to submit hours. I'd like to build a form that asks if they are new:

1. if no find their information already submitted (name, email) and then let them submit hours
2. if yes enter in their information and then let them submit hours

I know how to do #1, how could I do #2 allowing them to enter their new information?

Thanks!

Hmm, maybe you could have a checkbox field that asks "Are you new?", and if the user ticks that checkbox you can show all the other fields that you'd like them to fill up such as name, email, etc?

That way your existing volunteers can just skip that "Are you new" question, but new users will tick it and fill it up like you want
