The simplest way to do it is to set up a WhoAmI web service:

Conversation: User information in text boxes
Subject: User information in text boxes

Hi,

How do I populate text boxes with user data from the user who opens a
form
to fill it in.
What I would like to automatically be filled in is First Name, Last Name
and
E-mail address.

Regards,
Hasse
