I had 2 users from the HR roles. User1 will not be able to edit the unpublished node created by User2. I understand Drupal 5 allows edits rights for owner even if the node is unpublished. How can I enable users to edit (update/delete) unpublished nodes that belong to the same role?

I am not good at codings and I looked into this node but it was for Drupal 4.x:
http://drupal.org/node/41188
Wonder if this applies to Drupal 5.

Thank you.
