Autofill fields for logged-in users I have a content type with several fields; one field defines a postal address. If new content is created and the user has logged in, this field should be automatically filled with the address defined in the user profile. If a guest is creating new content, he will have to fill in the address by himself.

How I can achieve this? Are there any modules?
The Token module is a start, but it alone won't allow you to pre-fill the content.  By default it will provide a token for the value of every field defined in the user profile.
