A cache owner recently suggested that I add a find log on a missing cache of hers that I had previously logged as a DNF, since the cache wasn't there when I was searching, and was subsequently permanently archived. I have noticed other people doing that, but I didn't think it sounded quite right. I figure a DNF is a DNF, regardless of the reason. Although I think i was looking in the right place, who knows if would have found it where it there. Lots of times I've gone back for a DNF that was there, and have found it the second time. What's the etiquette?
