If I add a folder in my python code as follows (where users is where I wish to create this folder and username is to be the name of the folder): manage_addFolder(users, username, username) How do I go about changing the owner of that folder (to the user named by the 'username' variable)? If 'uF' is a handle to the folder object created above, the method: uF.changeOwnership(username) fails. It appears that changeOwnership() expects an actual user object and not the character string. I then tried using the 'getUser()' method to retrieve the user object associated w/ the name but keep getting NotImplentedErrors. Clearly I'm doing something pretty wrong here - the newest documentation I can find on the subject is the developers guide for Zope 2.4, which perhaps is out of date? Thanks -J
