I'm not in Feedback since I don't see it in the choices, after clicking on '+'.
I don't remember the technical name for the little icons at the bottom of each post … Lol, Agree, and so forth.
But given the forum wanting them, (1) they're tiny at least for me, (2) tastefully greyed-out to avoid noticing, and (3) it's not easy to see that posts get liked etc (the whole point). Basically, posts get commented, and then are ushered into the 'old posts home'.
Now, bigger icons might reduce the white space, so that's out.
But maybe bold the icon counts, when non-zero?
