Is there a way to know whic editor is editing what category ?

I am just asking if it is possible to know who is editing what .

No, not even editors can know who will be editing in which category.
The only thing we know is who can edit in a category.
But "can" and "will" are two completely different things.
Each category can be edited by some 200 editors.

The editor(s) (if there is a specific one) for a particular category is listed at the bottom of the category page. There is an additional smaller group of editors that can edit anywhere in the directory who are not so listed.

I would add that if you do not see an editor listed at the bottom of a category, you can move back on the tree until you come to an editor that can edit where they are listed and anywhere backwards to whence you came.

That make sense?

Also, don't think of the ODP like some kind of army-run assembly line where work-unit-number-1 is assigned to workstation-number-1, has to do all the work sent to WS1, and must take the blame for anything that goes wrong there.

It's based on PERMISSIONS, not ASSIGNMENTS.

Think of it like a game preserve, where different people have permissions to hunt different kinds of game. Permissions can overlap, and if some particular 12-point buck goes all season without being shotgunned, ... it's OK.

Who's hunting on the back forty today? We don't know, they didn't sign in with the guard. Who'll be hunting there tomorrow? We don't officially know (although Joe may have told me in strictest confidence that he hunts most Thursday afternoons--but I don't have the right to tell anyone else that.)

All we know is where people HAVE been hunting. But most successful hunter/gatherers move around a lot.
