Similar to the FTF Bookmark List, it would be very nice to have a Bookmark List where all Caches are saved that should be excluded from the Statistics.
For example I have found a cache in the USA that was part of a "Community Partnership" Thing: One multi cache was hidden in Germany and another in the USA. Both caches had the first stage and the final in the "own" country, but the second stage was in the other country. For example, we had here in Germany the first stage, but the found coordinates led to the US. So you needed a cacher in the USA that found the final coordinates there for you. Cachers there had the same situation so it resulted in finding a "partner" that gives you your final coordinates and you give hin your found final coordinates. And at the end, you sign both participants in the logbook as a "thank you", because both took part in both caches.
Long story short: I have logged the USA Cache as part of this partnership community thing, but I don't want it to be in my statistics as a physical cache.
Similar situation exists with many "couch potatoe" virtual caches that some cachers found before the guidelines changed.
I think it is not much afford to invent such an "exclude caches from statistics" list due to the existing FTF Bookmark include thing. I would be very happy :)
