We've implemented a new map moderation system--users can vote on map approval or disapproval (sort of like the old Minimod system), but enough votes in one direction will actually cause the resource to be approved or rejected respectively. A moderator's decision will override this, but likely will not need to.
Currently, a resource needs at least 10 votes to be approved and 20 to be rejected, and 75% of the votes to be in favour of one side for the resource to be approved or rejected respectively. These numbers are semi-random and subject to change as we see the system in action.
Please post questions, comments, and concerns about the system here.
