Exclude Node Author

Prevents authored on/by information from being displayed on a per node basis. Instead of hiding author information for an entire content type, can be hidden on just a single node. Designed for sticky nodes (but can be used anywehre) providing information about a page rather than used as content.

Based on: Exclude Node Title, except instead of excluding the Title, it excludes the "Submitted by" and "submitted on" information from being displayed on a per node basis.

Provides a checkbox on form node edit, to exclude submitted by/on from display.
