Node User is intended to allow nodes to act as users. It does this by creating a user for each node. This functionality can be configured by node type.
It works, but it is still under intensive development
--------------------------------------------
During the development phase:
The module checks whether the currently form has been changed before process of leaving / closing the overlay / form. When the form is not saved confirmation window is displayed with the text defined in it.
it allows to set up css class for changed elements, and (feature) revert element state.
