I'd just like to add my voice to the many who enjoy logging YOSM. This cache greatly enhances my caching experience. I know that many UK Cachers, and I'm sure the same is true for Canadian cachers and the Brass Cap series, base their caching activities almost entirely round the YOSM series and that, by effectively killing it off, Groundspeak is, and this is no exaggeration, ending their caching careers. This issue, which is close to my heart, together with the number of cache owners who like to use NM as a reminder to themselves that some action is required without having to disable the cache leads me, and the complications arising from adopted caches, to add my support to the solution already suggested, namely that a pop-up warning be implemented in the event of users attempting to use any of the lig types in the scope of this change. This would achieve the desired effect of preventing accidental double logging or choosing the wrong type through inexperience or mistake while allowing people to continue "playing the game their own way", preserving popular grandfathered caches and accomodating cache adopters and COs wishing to use NM for their own maintenance responsibilities.
