webforms submission email to (authenticated user) submitter


I am stuck with the Email handler of webforms submissions. I would like to send a confirmation email to the submitting user (only authenticated users are submitting). But I don’t seem to be able to get the place-holder for the “SEND TO” field right. It is not anything obvious to me, like:


or such. Perhaps I am missing something basic.

Note: since these are authenticated users, I do not want to make them fill out or tick an “Email” field in the webform. Therefore, I cannot take the Email address from the content. (Or can I?)

Anyway, thanks for your help!
