Thanks. I had gathered that, the case of Map Problems, "Not identified" means "escalate to a region-ignorant and possibly incompetent editor with unpredictable results". (Wouldn't that make a useful tooltip!)
However it sounds like you're saying that, in the case of User Requests, "Not identified" does NOT escalate; but rather it closes out the UR with a nice note to the requestor saying "sorry we can't see how to help resolve this" and that's it. Is that right? URs do not escalate regardless of whether they are "Solved" or "Not identified"?
