Since the portal I am developing do not require user to login and all portlets should maintain the same preferences at an instance level at all time. I just want to find an easy way for system admin to configure portlet instances. | | That should clear things up. Thanks for the reply :) isnt it what I suggested though the usage of edit_default in the instance configuration ?
