Challenge checker exceptions

Not all Geocaches are clear if they are a Challenge or not. Therefore Project-GC has built a Challenge Exception-system. A part of the community has been granted access to this system, and they read through cache description to add votes if they believe these Geocaches are Challenges or not. In here, they can discuss extreme cases and see if they can come to an agreement.

ARCHIVE Checker requests (completed)

Once a checker request has been fulfilled and the challenge owner (or checker requester) is satisfied the thread should be moved here by a moderator. Please allow some time before moving the thread, to allow feedback from the requester.

ARCHIVE Checker requests (impossible)

Moderators will move threads from "Checker requests" into this forum after a while when it has been decided that the challenge checker isn't possible for one or another reason. The threads should not be moved right away. The challenge owner should have a chance to adjust his requirements if that helps.
