I can't see them either. There's a bit that say Yay Nay under Karma - is that it? I'm using Chrome via Android phone.
@Bogwoppit , yes, that's it. Clicking the thumb up increases the count with the little green heart.
@jesster I'm using same Chrome on a late model Dell PC. You won't see it on your posts but on other members, hopefully, below their avatar and moniker.
@Francesca , I have no intentions of ever pressing that little thumb down. No no! But what happens when you do? Does it take one point away from the members total? I don't want to run an experiment on that to satisfy my curiosity.
