In D6 we could configure a webform field to pull profile data by using a token like %profile[key] and assigning the user field to the form (Details here). How can we to something similar in D7 using the user fields instead of the profile fields?
It appears that this can't be done using the standard webform module. It defines a limited list of tokens that hasn't been updated for the new user fields. They are included as tokens (if you use field_nnn) but they will be an empty value.
After initially looking at building a custom module, it seems that the Tokens module does make user fields available in the form [user:field_nnn].
The new Webform 4.x uses the token system. The ongoing process can be followed here
