"Organized"? How, where, and by whom? Is there a Facebook page or Twitter feed?
I wondered the same thing. I do not like Challenges counting as "Finds" and voted in the Feedback topic without any organized campaign contacting me about it. It is not because I do not like Challenges or are against them. Rather, I like challenging myself to try and get to different cache locations (i.e. counties, states, etc.), certain numbers, and other stats. If Challenges are counted as finds, but not supported through GSAK, it is going to screw up the game I play against myself.
As I could not care less about others' stats, the easy answer is not to do Challenges. I already refuse to log the bonus finds I have for caches. The problem is that Challenges might be fun and I would not mind doing some of them.
In the end, there is a place for Challenges. I expect my 10 year old nephew will really enjoy them. He only gets to go caching the couple of times a year we visit and complained recently that he has not been able to update his geocaching.com account for a couple of months. The Worldwide Challenges will allow him to do enjoy the game and the site without a GPSr. But, a "find" is exactly that - finding a cache, finding a location, etc.
