It would be nice one, for cleanliness on user side and also for posterity in the forums if we could somehow share an app to the forum and relinquish all ownership to the community as a static entity.
This would allow demo or help related apps to be created and shared without having to worry about them consuming account resources, cluttering my apps and becoming broken links during spring cleaning of unused apps.
Perhaps we could mark an app as community share and when/if this app is deleted from our personal library it would be transferred to a dummy account the automatically deletes apps that have not be access for more than X days.
