We are the Geocaching Association of Great Britain so I tend to agree with Chris that Munzees, Pokemon Go etc are outside our remit.
I am a member of Open Caching and Terracaching, as I joined them when I first started geocaching - but I have never searched for any of their caches as there are so few about. I also belong to Trigpointing and have claimed a few finds on there that I have found whilst geocaching!
I think it is important that we do draw cacher's attention to the other geocaching listing sites as otherwise they would not appreciate that we are independent of Groundspeak (Geocaching.com) who are a commercial organisation.
