Anonymous responses on Office forms: is there any way to have their email or name?

Damien_Rosario obviously there is no way to know who answered anonymously.  That is a truism.

The point of the original question is why can't we have attributed answers on a form that allows external conacts to answer.

Data protection and all that - we can't force people to give us their emails.  Absolutely right and how it should be.

But we aren't forcing them to answer.  They want to answer and they want us to know who the answer is coming from.

They should be able to waive their anonymity and provide us with their email address.  Without them having to type their email address in and potentially get it wrong.

Especially when we already have their email address - we sent them the link to the form in an email!!!

They are friendly contacts, volunteers and supporters of the charity, who send us information regularly.  But they are not allowed to tell us who they are by providing their email address!  What is this maddness?
