Shown on Special:ChallengeView when viewing a challenge that you won; this label-like message is followed by a drop-down menu (containing three possible rating options: challengeview-positive ("positive"), challengeview-neutral ("neutral") and challengeview-negative ("negative"))

"end" means "part"/"role" here, as in the expression "keeping your end of the bargain"
