Hello I always wish these two badges were included soon or later, I had suggested a way in the past, that was to tag the logs of night and scuba caches in a similar way it's done for FTFs, so that the system could see the log and count it, but the answer was that it should have been the cache to be tagged, not the log, so that everyone who logged it would have been awarded the badge.
Wiuld it be possible to do something similar to what they're already doing for challenges? Two lists checked by admins where are included only actual night and scuba caches, and log sent to caches in those lists will automatically be counted for the badge.
It shouldn't be so hard, should it? There are not many night caches around and even less scubas, and with the help of the users it should be quite easy to enlist them all.
