I was surfing the forums looking for something and came across this thread, very interesting. You have a challenge cache that has been archived but people want to adopt it and the reviewer will not allow it. I see pages of people wondering why it can't be done. Well it has been done,I'm not trying to beat a dead horse here but just go to GCG2VM or GCB5BF. Also go to the reviewers website wizardofooze.com and read about team KFWB. They are legendary on Vancouver Island. They started doing very complex and interesting caches at the very start of geocaching. Like GG , they got fed up with Groundspeak and earlier this year archived over 300 caches. There was such an outcry that Groundspeak unarchived some of them and let people adopt them. I think it depends on the cache, the cache owner and the reviewer, if they don't get along there could be a problem and than the "RULES" are enforced. I know I am comparing over 300 caches to 1 but they all are unique and mean something different for everybody, just my 2 cents........
