Background: This task is based on a wish that received 21 points (#9) in the German Community Wishlist. Originally, the wish was to receive an information about the sent messages. To keep the number of notifications smaller, and to help people use mentions in a way that they are sent, the task informs about mention failures, and adds the reasons for the failure as well.
