I just went to the GC forums and checked an event. The Found It log is gone from events, but the Attended log counts the same as the Found It. So It sounds like to log the caches we would have to use the Attended log.
In the forums all I could find were people whining that temp event caches don’t meet the GC.com criteria, so they shouldn’t be logged as finds. Which is kind of funny because I always thought it was the cache owner that decides what will or will not count as a find. It also reminded me why I avoid the GC forums.
