Discussion subitems with multiple names
Currently we create a subitem Discussion of the name of the item.
With different names for one item we create currently different subitems. This can be wanted.
I think we should offer an already existing Discussion page or give the user the choice to create a new one or use an existing one.
If a name becomes removed from the list, what should happen to the Discussion subitem? A notification for further cleanup, a meta entry, e.g. deprecated that helps to cleanup?
