Sorry for wasting your time reading these two emails, I finally googled
successfully for an answer.
For those interested: $node->field_proprio[0]['uid']

I'm sure there are many other veery interesting things in Drupal. As I
have a little problem to read big docs on-screen, does anyone have a
good book recommandation for people who know want to do advanced things
(like module creation) with Drupal ?

Thanks,
