Assignment

Hello all,
I am trying to get some things setup using moodle, one of my goals is to create a document for each member, but to edit the document, I only want to allow certain people permission to do so, not to include the person who the document is on. How can I do this?
I am the training officer for a fire department in Georgia, we have "task books" that must be completed each year. Each firefighter has a task book that his/her supervisor must complete. I would like to put this online under moodle if possible but the supervisor would need edit permission not the individual firefighter.
Thank you,
Skip
