What is the general rule for posting "did not find"s?. I realise that if I am looking for a traditional cache, and do not locate it I post a DNF on the cache page, but what is the rule if I am working on a multi or puzzle cache and may have been out collecting the answers to the questions but havent looked for the final cache, do I post a DNF or do I wait to post any response to the page until I have looked for the final co-ordinates. I have had a couple where I have run out of time or started looking to late in the day, so not sure what to do
