The reputation points are gained when someone chooses one of those little 'reaction' icons on their post. ZG added a 'like' blue star to Fern's post, giving her another reputation point.
Fern, I don't understand why you can't see these; I've double checked your permission set. I'll try again.
You should be seeing these, Fern, can you try another browser? Also, if you have the screen resolution too large, as in to make things larger, it might disappear off the page. I was having this problem on a laptop.
