That shows your reputation status. You "have made some friends around here".
If you click on the
Account button in the toolbar just above the thread, and then scroll down to the bottom of the page, you will see a window headed "Latest Reputation Received". Next to the title is the number of points you have. The table below that shows who has given you reputation points, when, and for what thread/post.
The text that appears when someone mouses-over the square green dot changes, according to how many points you have. You can add to someone's reputation by clicking on the scales icon (looks like a Libra zodiac sign) next to the post number of their post.
