I have searched in Google with queries like "User reference drupal 7" or "User taxonomy vocabulary drupal" "user field drupal 7" "cck drupal 7" but I couldn't find any way to make a field that links for a user profile page... Do you know how to make this as a simple field can be done with CCK in Drupal 6? thanks.
You may look into References module
This project provides D7 versions of the 'node_reference' and 'user_reference' field types, that were part of the CCK package in D6, at functional parity with the D6 counterparts.
Another alternative to References is the Entity Reference module. It can do user reference fields as well.
