The one in the middle says if you click on it, "add to *whomever poster is* reputation. When you click on it, you can click, "approve" or "disappove" of the that persons post and leave a comment.
I was curious as well and tried to read up in the FAQ for info about it myself. Say you disapprove or approve of a posters reply, who reads that and where do the comments go? I clicked on mine and it says, "You have 10 reputation points", what does that mean? I've only posted twice, this makes 3. Are they good rep points or bad?
I too am curious what it is and how it works. What if someone dislikes another poster(it does happen as we all know) and keeps clicking, "Disapprove" of a that persons post, what happens? Do they get some thing under their names?
Questions, Questions, Questions, I know, LOL! Knowledge is power and I am a curious one!
