"Thanks" is not the same as Karma. Good clarifying question. I attached a screen shot showing where each of them is placed in the forum. The "Karma" feature existed way before the "Thank You" feature. One is sorta for reputation, the other is for showing ones appreciation. Perhaps the app ought to have both "thanks" and "karma" as a configurable option (yes/no for display). This way if the admin has "karma" or "thanks" disabled in Kunena, they could remove it's display in the app as well.
