I have created a node as webmaster user and set no-webmaster user as node owner. The node created has no comments support, and I want to keep this way, but when node owned change something drupal adds comment support for node. The node is a story, and i cant to disable comments on "coment > setting" cause I need some stories created by users with comment support.

There are any easy way to create a new node type as story clone (this may be a solution) ?
