I would strongly appreciate the implementation of an icon on the Groundspeak website for explicit night caches.
It often happens that I want to do a cache by night and try to find night caches - but as they are not yet marked and categorized as explicit night caches this is nearly impossible.
Because of this I would really be glad if that option would be invented. I think of just clicking a checkbox when reporting a new cache: explicit night cache yes/no.
Should be not that difficult...
