Mates is there's a way to delete merit given? How it is?
There is no way to delete this. When sending merits, a new page opens up. Thus, you cannot give a member merit by mistake.
Sometimes it was happen due too poor connection, all I know I give merits to those who have a quality poster but after review I give it to users who can't deserve it. However thanks for your information, now I need to make sure that I can't send a merit to the users who not deserve it.
