This really isn't a question, more a call to arms.
Most of you probably know what a challenge cache is. You might also be aware of the fact that sometimes geocaches are Unknowns with the word Challenge in the name, even though they aren't a challenge. The opposite also exists, geocaches that are challenges, but don't have a proper name.
To determine if a cache really is a challenge, Project-GC has something called Challenge exceptions. This is a list of exceptions. Users who are moderators for this can add exceptions to the list, and the community then votes if it's a challenge or not. For example, if two users vote It's not a challenge while seven users vote It's a challenge, it's likely to be a challenge.
We then calculate a certainty score from the votes with a similar formula (the same actually) that we calculate FP Wilson Score with. As it is today, if the certainty is >= 32%, we trust the votes.
We currently have around 30 users who has permission to give these votes, and are looking for a few more volunteers. It would be extra interesting to get volunteers who speaks other languages than Swedish and English for example, since it's obviously easier to understand if it's a challenge or not when you speak the language.
Currently there are almost 2000 exceptions in the list, over 6000 votes has been placed to determine if these are challenges or not.
We are planning to increase the required certainty from 32% to 35%, but before we do that, there are 93 exceptions that needs additional voting (to get 35% or above). 93 isn't a lot to be honest. I have myself been doing a handful a day for a week now.
Anyway, if you are interested in helping out maintaining this list you need permission. Just answer with a comment or answer in this thread the coming 1-2 weeks and we will grant you permission.
